How does one love Allah

Bismillah irrahman irrahim

Assalamu alaikum

Some companions once said to Sayyidina Muhammad sallallahu alayhi wassalam, "Ya rasullullah, we love Allah subhanahu wa ta'ala. Does Allah subhanahu wa ta'ala loves us as much as we love Him". Upon this the Ayah was revealed 3:31] Say, (O Muhammad, to mankind): If ye love Allah, follow me; Allah will love you and forgive you your sins. Allah is Forgiving, Merciful.
and we should remember the saying of Ayeshah (ra), the wife of Sayyidina Muhammad sallallahu alayhi wassalam when some one asked her about the character of The Prophet, she said, 'His character is that of Holy Quran'.

So if we have Love of our Lord in our heart then all we need to do is get better understanding of Holy Quran and learn the sunnah of Sayyidina Muhammad sallallahu alayhi wassalam and follow it to best of our capability.

I cant see whether some1 has replied to your question about 'saw'. This is shorthand for sallallahu alayhi wassalam which means 'may peace and blessing of Allah subhanahu wa ta'ala be upon him'. This is used for Prophet Muhammad sallallahu alayhi wassalam. While we write Allah subhanahu wa ta'ala, swt for short which means Glorified and Most High.

Lastly you mentioned the dificulty you facing knowing what to say in the salah (prayer) and worrying about what is in your heart. I think if you try to ponder over the meaning of what you saying, you would be surprised to know how much it is tuned up with your heartbeat. The first Surah that we read in the salah is a coversation between us and our Lord. There is a beautiful saying of Sayyidina Muhammad sallallahu alayhi wassalam about this surah and i posted in 'Quran and Sunnah' section quite a while ago.

Al-Fatihah and the Prayer

Muslim recorded that Abu Hurayrah said that the Prophet said,

(Whoever performs any prayer in which he did not read Umm Al-Qur'an, then his prayer is incomplete.) He said it thrice.

Abu Hurayrah was asked, "[When] we stand behind the Imam'' He said, "Read it to yourself, for I heard the Messenger of Allah say,

(Allah, the Exalted, said, `I have divided the prayer (Al-Fatihah) into two halves between Myself and My servant, and My servant shall have what he asks for.' If he says,

(All praise and thanks be to Allah, the Lord of existence.)

Allah says, `My servant has praised Me.' When the servant says,

(The Most Gracious, the Most Merciful.)

Allah says, `My servant has glorified Me.' When he says,

(The Owner of the Day of Recompense.) Allah says, `My servant has glorified Me,' or `My servant has related all matters to Me.' When he says,

(You (alone) we worship, and You (alone) we ask for help.) Allah says, `This is between Me and My servant, and My servant shall acquire what he sought.' When he says,

(Guide us to the straight path. The way of those on whom You have granted Your grace, not (the way) of those who earned Your anger, nor of those who went astray), Allah says, `This is for My servant, and My servant shall acquire what he asked for.').''

These are the words of An-Nasa'i, while both Muslim and An-Nasa'i collected the following wording, "A half of it is for Me and a half for My servant, and My servant shall acquire what he asked for.''
