Bi ismillahir rahmanir raheem

assalamu alaikum

This is some of the evidence upon which the scholars understanding of jinn and shaytan is based on

Jinn

Book - "The World of the Jinn and Devils", p. 7
Ibn Abdul Barr said, "The jinn, according to the scholars of the language, are of different types:

1. If one is mentioning the jinn purely of themselves, the are called jinni.*
2. If one is mentioning the jinn that live among mankind, they are called aamar whose plural is amaar.
3. If one is mentioning the ones that antagonize the young, they are called arwaah.
4. If one is mentioning the evil ones that antagonize humans they are called shaitan for the singular [and shayateen for plural].
5. If they cause even more harm and become strong, they are called afreet."**

*Notice the similar sound between jinni and english's "genie". TV and other media have twisted the concept of jinn; however, it is interesting to note its origin is from Islam. "I Dream of Jeannie" is a TV show based around a Genie (jinni, plural of jinn).  In this show, Jeannie, the genie, frequently was given a request and the requestor never quite got what was requested as she was always creating unintentional mischief.  However we understand that the shaitan among the jinn antagonize humans, not that they are kind beings who accidentally mess up on occasion.  Those who seek aid (such as asking for favors or making request) from the jinni will find deception and a twisted type of aid that doesn't really meet the requestor's original request, but that satisfies the shaytaanic jinn's desire for evil.

**An Ifr�t (strong) from the jinns said: "I will bring it to you before you rise from your place (council). And verily, I am indeed strong, and trustworthy for such work." [The Noble Qur'an 27:39]

Narration - Reported by al-Tahhaawi in Mushkil al-Athaar, 4/95, and by al-Tabaraani in al-Kabeer, 22/214

Abu Tha�labah al-Khushani said: �The Messenger of Allaah http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said: �The jinn are of three types: a types that has wings, and they fly through the air; a type that looks like snakes and dogs; and a type that stops for a rest then resumes its journey.� [Shaykh al-Albaani said in al-Mishkaat (2/1206, no. 4148): al-Tahhaawi and Abu�l-Shaykh reported it with a saheeh isnaad]

The Origin of the Jinn

The jinn are NOT fallen angels.  They were created from a smokeless flame of fire. The first recorded jinn to be disobedient is Iblis.  Disbelieving, disobedient jinn and humans are known as shayateen (satans).

The Noble Qur'an - Ar-Rahmaan 55:15, 15

He created man (Adam) from sounding clay like the clay of pottery.

And the jinns did He create from a smokeless flame of fire.

The Noble Qur'an - Al-Hijr 15:26-42

26. And indeed, We created man from sounding clay of altered black smooth mud.

27. And the jinn, We created aforetime from the smokeless flame of fire.

28. And (remember) when your Lord said to the angels: "I am going to create a man (Adam) from sounding clay of altered black smooth mud.

29. "So, when I have fashioned him completely and breathed into him (Adam) the soul which I created for him, then fall (you) down prostrating yourselves unto him."

30. So, the angels prostrated themselves, all of them together.

31. Except Ibl�s (Satan), - he refused to be among the prostrators.

32. (All�h) said: "O Ibl�s (Satan)! What is your reason for not being among the prostrators?"

33. [Ibl�s (Satan)] said: "I am not the one to prostrate myself to a human being, whom You created from sounding clay of altered black smooth mud."

34. (All�h) said: "Then, get out from here, for verily, you are Raj�m (an outcast or a cursed one)." [Tafs�r At-Tabar�]

35. "And verily, the curse shall be upon you till the Day of Recompense (i.e. the Day of Resurrection)."

36. [Ibl�s (Satan)] said: "O my Lord! Give me then respite till the Day they (the dead) will be resurrected."

37. All�h said: "Then, verily, you are of those reprieved,

38. "Till the Day of the time appointed."

39. [Ibl�s (Satan)] said: "O my Lord! Because you misled me, I shall indeed adorn the path of error for them (mankind) on the earth, and I shall mislead them all.

40. "Except Your chosen, (guided) slaves among them."

41. (All�h) said: "This is the Way which will lead straight to Me."

42. "Certainly, you shall have no authority over My slaves, except those who follow you of the Gh�w�n (Mushrik�n and those who go astray, criminals, polytheists, and evil-doers, etc.).

Solomon's Experience with the Jinn

Allah made all the jinn subservient to the Prophet Sulaimaan (Solomon), a gift from Allah, swt, that will never be granted to another after him.

The Noble Qur'an - Saad 38:35-39
35. He said: "My Lord! Forgive me, and bestow upon me a kingdom such as shall not belong to any other after me: Verily, You are the Bestower."

36. So, We subjected to him the wind, it blew gently to his order whithersoever he willed,

37. And also the Shay�tin (devils) from the jinns (including) every kind of builder and diver,

38. And also others bound in fetters.

39. [Saying of All�h to Sulaim�n (Solomon)]: "This is Our gift, so spend you or withhold, no account will be asked."

The Noble Qur'an - Saba' 34:12-14

12. And to Solomon (We subjected) the wind, its morning (stride from sunrise till midnoon) was a month's (journey), and its afternoon (stride from the midday decline of the sun to sunset) was a month's (journey i.e. in one day he could travel two months' journey). And We caused a fount of (molten) brass to flow for him, and there were jinns that worked in front of him, by the Leave of his Lord, and whosoever of them turned aside from Our Command, We shall cause him to taste of the torment of the blazing Fire.

13. They worked for him what he desired, (making) high rooms, images, basins as large as reservoirs, and (cooking) cauldrons fixed (in their places). "Work you, O family of D�wud (David), with thanks!" But few of My slaves are grateful.

14. Then when We decreed death for him [Sulaim�n (Solomon)], nothing informed them (jinns) of his death except a little worm of the earth, which kept (slowly) gnawing away at his stick, so when he fell down, the jinns saw clearly that if they had known the unseen, they would not have stayed in the humiliating torment.

The Noble Qur'an - An-Naml 27:17-19

17. And there were gathered before Sulaim�n (Solomon) his hosts of jinns and men, and birds, and they all were set in battle order (marching forwards).

18. Till, when they came to the valley of the ants, one of the ants said: "O ants! Enter your dwellings, lest Sulaim�n (Solomon) and his hosts crush you, while they perceive not."

19. So he [Sulaim�n (Solomon)] smiled, amused at her speech[] and said: "My Lord! Inspire and bestow upon me the power and ability that I may be grateful for Your Favours which You have bestowed on me and on my parents, and that I may do righteous good deeds that will please You, and admit me by Your Mercy among Your righteous slaves."

Every human has a partner Jinn

(Ibn As-Sinni)

Hadith - Ahmad, an-Nasa'i, Dawud, al-Hakim and al-Baihaqi
Qatadah related from 'Abdullah ibn Sarjas who said, "The Messenger of Allah forbade urination into a hole." Said Qatadah, "What is disliked about urinating into a hole?" Said he, "It is the residence of the jinn." [Ibn Khuzaimah and Ibn as-Sakin classified it as sahih]

More About the Jinn

Hadith - Sahih Bukhari 4:533, Narrated Jabi bin 'Abdullah http://muttaqun.com/dictionary3.html#May%20Allah%20be%20pleased%20with%20him">

The Prophet http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said, "Cover your utensils and tie your water skins, and close your doors and keep your children close to you at night, as the Jinns spread out at such time and snatch things away. When you go to bed, put out your lights, for the mischief-doer (i.e. the rat) may drag away the wick of the candle and burn the dwellers of the house." Ata said, "The devils." (instead of the Jinns).

Hadith - Sunan of Abu Dawood, Narrated Abu Sa'id al-Khudri
Muhammad ibn AbuYahya said that his father told that he and his companion went to AbuSa'id al-Khudri to pay a sick visit to him. He said: Then we came out from him and met a companion of ours who wanted to go to him. We went ahead and sat in the mosque. He then came back and told us that he heard AbuSa'id al-Khudri say: The Apostle of Allah http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said: Some snakes are jinn; so when anyone sees one of them in his house, he should give it a warning three times. If it return (after that), he should kill it, for it is a devil.

Hadith - Al-Muwatta 54.33

[Transmitted by Tirmidhi, Nasa'i with this exception that he did not make mention of: The Food of your brothers from amongst the jinn.]

The Noble Qur'an - Ar-Rahmaan 55:56
Wherein both will be those (maidens) restraining their glances upon their husbands, whom no man or jinn yatmithhunna (has opened their hymens with sexual intercourse) before them.

Hadith - Abu Dawood 1046, Narrated Ali ibn Abu Talib

Ali said on the pulpit in the mosque of Kufah: When Friday comes, the devils go to the markets with their flags, and involve people in their needs and prevent them from the Friday prayer. ...

Allah will fill Hell with jinns and men all together

The Noble Qur'an - As-Saaffaat 37:158
And they have invented a kinship between Him and the jinns, but the jinns know well that they have indeed to appear (before Him) (i.e. they will be brought for accounts).

The Noble Qur'an - Huud 11:119
Except him on whom your Lord has bestowed His Mercy (the follower of truth - Isl�mic Monotheism) and for that did He create them. And the Word of your Lord has been fulfilled (i.e. His Saying): "Surely, I shall fill Hell with jinns and men all together."

The Noble Qur'an - Al-An'aam 6:130, 131
O you assembly of jinns and mankind! "Did not there come to you Messengers from amongst you, reciting unto you My Verses and warning you of the meeting of this Day of yours?" They will say: "We bear witness against ourselves." It was the life of this world that deceived them. And they will bear witness against themselves that they were disbelievers.

This is because your Lord would not destroy the (populations of) towns for their wrong�doing (i.e. associating others in worship along with All�h) while their people were unaware (so the Messengers were sent).

The Noble Qur'an - Al-A'raaf 7:179
And surely, We have created many of the jinns and mankind for Hell. They have hearts wherewith they understand not, they have eyes wherewith they see not, and they have ears wherewith they hear not (the truth). They are like cattle, nay even more astray; those! They are the heedless ones.

Fortune-tellers/Soothsayers

Hadith - Al-Bukhari 7.657, Narrated 'Aisha, r.a.
Some people asked Allah's Apostle (saaws) about the foretellers. He said. -They are nothing." They said, -O Allah's Apostle! Sometimes they tell us of a thing which turns out to be true." Allah's Apostle said, "A Jinn snatches that true word and pours it into the ear of his friend (the foreteller) (as one puts something into a bottle). The foreteller then mixes with that word one hundred lies."

Muslim Jinn

The Noble Qur'an - Az-Zaariyaat 51:56
And I (All�h) created not the jinns and humans except they should worship Me (Alone).

Hadith - Tirmidhi #861, Narrated Jabir ibn Abdullah, Tirmidhi reported and said: This is a gharib hadith.

Allah's Messenger http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> came out to his companions and recited Surah ar-Rahman (55) from the beginning to the end, but they remained silent. Thereupon he said: I recited this before the Jinn on the night of Jinn, and their response was better than that of yours. When I came to these words: `Then which of the favours of your Lord do you deny?' They said: Our Lord, there is nothing that we deny of Thy favour; to Thee is praise due.

The Noble Qur'an - Al-Jinn 72:1-14

1. Say (O Muhammad http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> ): "It has been revealed to me that a group (from three to ten in number) of jinns listened (to this Qur'�n). They said: 'Verily! We have heard a wonderful Recital (this Qur'�n)!
2. 'It guides to the Right Path, and we have believed therein, and we shall never join (in worship) anything with our Lord (All�h).
3. 'And exalted be the Majesty of our Lord, He has taken neither a wife, nor a son (or offspring or children).
4. 'And that the foolish among us [i.e. Ibl�s (Satan) or the polytheists amongst the jinns] used to utter against All�h that which was wrong and not right.
5. 'And verily, we thought that men and jinns would not utter a lie against All�h.
6. 'And verily, there were men among mankind who took shelter with the masculine among the jinns, but they (jinns) increased them (mankind) in sin and disbelief.
7. 'And they thought as you thought, that All�h will not send any Messenger (to mankind or jinns).
8. 'And we have sought to reach the heaven; but found it filled with stern guards and flaming fires.
9. 'And verily, we used to sit there in stations, to (steal) a hearing, but any who listens now will find a flaming fire watching him in ambush.
10. 'And we know not whether evil is intended for those on earth, or whether their Lord intends for them a Right Path.
11. 'There are among us some that are righteous, and some the contrary; we are groups each having a different way (religious sect, etc.).
12. 'And we think that we cannot escape (from the punishment of) All�h in the earth, nor can we escape (from the punishment) by flight.
13. 'And indeed when we heard the Guidance (this Qur'�n), we believed therein (Isl�mic Monotheism), and whosoever believes in his Lord shall have no fear, either of a decrease in the reward of his good deeds or an increase in punishment for his sins.
14. 'And of us some are Muslims (who have submitted to All�h, after listening to this Qur'�n), and of us some are Al-Q�sit�n (disbelievers those who have deviated from the Right Path)'. And whosoever has embraced Isl�m (i.e. has become a Muslim by submitting to All�h), then such have sought the Right Path."

Shaytaan

The shaytaan (satan) can be human or jinn...

The Noble Qur'an - Al-An'aam 6:112
And so We have appointed for every Prophet enemies - Shay�tin (devils) among mankind and jinns, inspiring one another with adorned speech as a delusion (or by way of deception). If your Lord had so willed, they would not have done it, so leave them alone with their fabrications.

Know your enemy...

The Noble Qur'an - Faatir 35:6
Surely, Shait�n (Satan) is an enemy to you, so take (treat) him as an enemy. He only invites his Hizb (followers) that they may become the dwellers of the blazing Fire.

The Noble Qur'an - Az-Zukhruf 43:62
And let not Shait�n (Satan) hinder you (from the right religion, i.e. Isl�mic Monotheism), Verily, he (Satan) to you is a plain enemy.

Shaitaan tells you to fear people instead of Allah, swt...

The Noble Qur'an - Az-Zukhruf 43:62
It is only Shait�n (Satan) that suggests to you the fear of his http://muttaqun.com/auliya.html - Auliy� ' [supporters and friends (polytheists, disbelievers in the Oneness of All�h and in His Messenger, Muhammad http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> )], so fear them not, but fear Me, if you are (true) believers.

The jinn's power is to Whisper/Deceive

The Noble Qur'an - An-Naas 114

1. Say: "I seek refuge with (All�h) the Lord of mankind,

2. "The King of mankind,

3. "The Il�h (God) of mankind,

4. "From the evil of the whisperer (devil who whispers evil in the hearts of men) who withdraws (from his whispering in one's heart after one remembers All�h),

5. "Who whispers in the breasts of mankind,

6. "Of jinns and men."

The Noble Qur'an - Al-An'aam 6:128
And on the Day when He will gather them (all) together (and say): "O you assembly of jinns! Many did you mislead of men," ...

The Noble Qur'an - Al-'Anaam 6:112
And so We have appointed for every Prophet enemies - Shay�tin (devils) among mankind and jinns, inspiring one another with adorned speech as a delusion (or by way of deception)....

The Noble Qur'an - An-Nahl 16:99-100
Verily! He has no power over those who believe and put their trust only in their Lord (All�h).

His power is only over those who obey and follow him (Satan), and those who join partners with Him (All�h) [i.e. those who are Mushrik�n - polytheists - see Verse 6:121].

The Noble Qur'an - Ibrahiim 14:22
And Shait�n (Satan) will say when the matter has been decided: "Verily, All�h promised you a promise of truth. And I too promised you, but I betrayed you. I had no authority over you except that I called you, so you responded to me. So blame me not, but blame yourselves. I cannot help you, nor can you help me. I deny your former act in associating me (Satan) as a partner with All�h (by obeying me in the life of the world). Verily, there is a painful torment for the Z�lim�n (polytheists and wrong-doers, etc.)."

The Noble Qur'an - Al-Israa' 17:61-65
And (remember) when We said to the angels: "Prostrate unto Adam." They prostrated except Ibl�s (Satan). He said: "Shall I prostrate to one whom You created from clay?"

[Ibl�s (Satan)] said: "See? This one whom You have honoured above me, if You give me respite (keep me alive) to the Day of Resurrection, I will surely seize and mislead his offspring (by sending them astray) all but a few!"

(All�h) said: "Go, and whosoever of them follows you, surely! Hell will be the recompense of you (all) an ample recompense.

"And Istafziz [literally means: befool them gradually] those whom you can among them with your voice (i.e. songs, music, and any other call for All�h's disobedience), make assaults on them with your cavalry and your infantry, mutually share with them wealth and children (by tempting them to earn money by illegal ways usury, etc., or by committing illegal sexual intercourse, etc.), and make promises to them." But Satan promises them nothing but deceit.

"Verily! My slaves (i.e the true believers of Isl�mic Monotheism), you have no authority over them. And All-Sufficient is your Lord as a Guardian."

Supplication for one afflicted by whisperings in prayer or recitation...

Hadith - Sahih Muslim 5463, Narrated Uthman ibn Abul'As, r.a.
Uthman came to Allah's Messenger http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> and said: Allah's Messenger, the Satan intervenes between me and my prayer and my reciting of the Qur'an and he confounds me. Thereupon Allah's Messenger http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said: That is (the doing of the Satan) who is known as Khinzab, and when you perceive its effect, seek refuge with Allah from it and spit* three times to your left. I did that and Allah dispelled that from me.

* this is a dry spit in the air

Seeking refuge IN the Jinn

The Noble Qur'an - Al-Jinn 72: 6-7
6. 'And verily, there were men among mankind who took shelter with the masculine among the jinns, but they (jinns) increased them (mankind) in sin and disbelief.

7. 'And they thought as you thought, that All�h will not send any Messenger (to mankind or jinns).

The Noble Qur'an - Ibrahiim 14:22
And Shait�n (Satan) will say when the matter has been decided: "Verily, All�h promised you a promise of truth. And I too promised you, but I betrayed you. I had no authority over you except that I called you, so you responded to me. So blame me not, but blame yourselves. I cannot help you, nor can you help me. I deny your former act in associating me (Satan) as a partner with All�h (by obeying me in the life of the world). Verily, there is a painful torment for the Z�lim�n (polytheists and wrong-doers, etc.)."

The Noble Qur'an - Al-An'aam 6:100-102
100. Yet, they join the jinns as partners in worship with All�h, though He has created them (the jinns), and they attribute falsely without knowledge sons and daughters to Him. Be He Glorified and Exalted above (all) that they attribute to Him.

101. He is the Originator of the heavens and the earth. How can He have children when He has no wife? He created all things and He is the All-Knower of everything.

102. Such is All�h, your Lord! L� il�ha illa Huwa (none has the right to be worshipped but He), the Creator of all things. So worship Him (Alone), and He is the Wak�l (Trustee, Disposer of affairs, Guardian, etc.) over all things.

The Noble Qur'an - Al-An'aam 6:128
And on the Day when He will gather them (all) together (and say): "O you assembly of jinns! Many did you mislead of men," and their Auliy�' (friends and helpers, etc.) amongst men will say: "Our Lord! We benefited one from the other, but now we have reached our appointed term which You did appoint for us." He will say: "The Fire be your dwelling�place, you will dwell therein forever, except as All�h may will. Certainly your Lord is All�Wise, All�Knowing."

Seeking refuge FROM the Evil Jinn

Say " 'audhu billah" (I seek refuge in Allah) and other dhikr (remembrance of Allah, swt) when the evil whisper of Shaitaan comes upon you, such as

• when becoming angry,
• having confusing or disobedient thoughts,
• when approached by arrogants who dispute the Truth of the ayats of Allah, swt,
• when about to recite Qur'an,
• or when in any situation that Quran and Sunnah teaches you is a result of the shaitaan.

The Noble Qur'an - Fussilat 41:36
And if an evil whisper from Shait�n (Satan) tries to turn you away (O Muhammad SAW) (from doing good, etc.), then seek refuge in All�h. Verily, He is the All-Hearer, the All-Knower.

The Noble Qur'an - Al-A'raaf 7:200, 201
And if an evil whisper comes to you from Shait�n (Satan) then seek refuge with All�h. Verily, He is All-Hearer, All-Knower.

Verily, those who are Al-Muttaq�n (the pious - see V.2:2), when an evil thought comes to them from Shait�n (Satan), they remember (All�h), and (indeed) they then see (aright).

The Noble Qur'an - Ghaafir 40:56
Verily, those who dispute about the Ay�t (proofs, evidences, verses, lessons, signs, revelations, etc.) of All�h, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad SAW) as a Messenger of All�h and to obey you]. They will never have it (i.e. Prophethood which All�h has bestowed upon you). So seek refuge in All�h (O Muhammad SAW from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.

The Noble Qur'an - An-Nahl 16:98
So when you want to recite the Qur'�n, seek refuge with All�h from Shait�n (Satan), the outcast (the cursed one).

Hadith - Al-Muwatta 51.10
Yahya related to me from Malik that Yahya ibn Said said, "When the Messenger of Allah http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> was taken on the Night Journey, he saw an evil jinn seeking him with a torch of fire.

The Messenger of Allah http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said, 'Yes, indeed.' Jibril said, 'Say, 'I seek refuge with the Noble Face of Allah and with the complete words of Allah which neither the good person nor the corrupt can exceed, from the evil of what descends from the sky and the evil of what ascends in it, and from the evil of what is created in the earth and the evil of what comes out of it, and from the trials of the night and day, and from the visitations of the night and day, except for one that knocks with good, O Merciful!"

Allah's Messenger http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said: The screen between the eyes of Jinn and the private parts of the sons of Adam as one of them enters the privy is that he should say: In the name of Allah. [This hadith has been transmitted by Tirmidhi and he said: It is a gharib hadith and its isnad is not sound.]

[Bismillahi] Allahumma inna 'audhu bika minal khubthi wal khabaa'ith.

[By the Name of Allah]. Oh Allah, I seek protection in You from unclean spirits, male and female.  [Abu Dawud 4/264, Ahmad 2/389]

The ayat "Al-Kursi" (2:255) is well-known as a means for repelling mischievious jinn...

The Noble Qur'an - Al-Baqara 2:255
Allah! La ilaha illa Huwa (none has the right to be worshipped but He), the Ever, Living, the One Who sustains and protects all that exists.  neither slumber, nor sleep overtake Him.  To Him belongs whatever is in the heavens and whatever is on earth.  Who is he that can intercede with Him except with His Permission?  He knows what happens to them (His creatures) in this world, and what will happen to them in the Hereafter.  And they will never compass anything of His Knowledge except that which He wills.  His Kursi extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them.  And He is the Most High, the Most Great (Ayat-ul-Kursi).

Hadith - Tirmidhi #2173, Narrated Jubayr ibn Nufayr  [Darimi transmitted it in mursal form].
Allah's Messenger http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said, "Allah finished Surat al-Baqarah with two verses which I have been given from His treasure which is under the Throne; so learn them and teach them to your womenfolk, for they are a blessing, a means of a approach (to Allah) and a supplication."

Ibn Taimiya, Majmu, vol. 19, p. 55
"The numerous people who have experienced these events all confirm the amazing effectiveness of this verse in warding off jinn and breaking their spells.  It [editor's note: ayat al-Kursi] has a great effect in repelling devils from humans, from the possessed and from those picked out by jinn, such as wrongdoers, people with bad tempers, those who follow their desires and lusts, musicians and those who become ecstatic through whistling and clapping.  If these verses are read over them with sincerity to Allah, the jinn will leave.  It will put an end to the mirages created by the jinn.  It will also disclose the falseness of those, the brothers of the jinn, who perform miraculous acts.  The jinn inspire their devotees with some knowledge that the ignorant think are miracles that Allah grants His pious servants.  In fact, they are simply Shaytaan's acts of deception over his devotees, of those whom have earned Allah's wrath and those who have gone astray."

Hadith - Tirmidhi #2145, Narrated An-Nu'man ibn Bashir
Allah's Messenger http://muttaqun.com/dictionary3.html#May%20Allah%27s%20peace%20and%20blessings%20be%20on%20him"> said, "Two thousand years before creating the heavens and the Earth, Allah inscribed a book of which He sent down two verses with which He concluded surat al-Baqarah. The Devil will not come near a house in which they are recited three nights." [Tirmidhi and Darimi transmitted it, Tirmidhi saying this is a gharib tradition.]

Make du'a (supplication) such as the following:

The Noble Qur'an - Al-Baqarah 2:286
All�h burdens not a person beyond his scope. He gets reward for that (good) which he has earned, and he is punished for that (evil) which he has earned. "Our Lord! Punish us not if we forget or fall into error, our Lord! Lay not on us a burden like that which You did lay on those before us (Jews and Christians); our Lord! Put not on us a burden greater than we have strength to bear. Pardon us and grant us Forgiveness. Have mercy on us. You are our Maul� (Patron, Supporter and Protector, etc.) and give us victory over the disbelieving people."

Recite Surahs Al-Falaq (Chapter 113) and An-Nas (Chapter 114)..
