- وَمَا أَرْسَلْنَاكَ إِلَّا رَحْمَةً لِّلْعَالَمِينَ

"Indeed, in this [Quran] is notification for a worshiping people. And We have not sent you, [O Muhammad], except as a mercy to the worlds." (Quran: 21:106-107)

God's Messenger was the kindest of men in the same way as he excelled all others in courage and valor. Being extremely kind-hearted, his eyes brimmed with tears at the slightest sign of inhumanity. 

Aishah the wife of the Prophet narrates that the Messenger of God said:

God is Kind and He loves kindness, and confers upon kindness which He does not confer upon severity, and does not confer upon any thing besides it (kindness). -Muslim

A Mercy for the Believers 

The Messenger's (PBUH) compassion towards the believers was of the utmost degree. The Quran describes his compassion in the following verse, which means:

"There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you [i.e., your guidance] and to the believers is kind and merciful." (Quran: 9:128)

Sa'd bin 'Ubaadah once became ill, so Allah's Messenger visited him in his house. On seeing his faithful Companion in a pitiful state, he was moved to tears. Then, he said: "Allah does not punish because of tears, nor because of grief, but he punishes because of this."- and he pointed to his tongue. (Al-Bukhari)

A Mercy Towards his Enemies

The prisoners of war taken captive at the battle of Badr were amongst his bitterest enemies. Nevertheless, he made sure that they were given the best of treatment. Among them was Suhayl bin 'Amr who was a fiery speaker and was denouncing the Prophet (PBUH). 'Umar one the Prophet's (PBUH) closest companions, suggested that two of his lower teeth be pulled out so that he might not be so vile in his speeches. The Prophet (PBUH) replied: "Were I to do this, Allah would disfigure me on the Day of Judgment, despite the fact that I am His messenger." (Hadith)

In Makkah, his people inflicted him with every kind of suffering, eventually forcing him to emigrate to Madinah, and then waged war on him for five years. However, when he conquered Makkah without bloodshed in the twenty-first year of his Prophethood, he asked the Makkan unbelievers who were awaiting his decision about them: "How do you expect me to treat you?" They responded unanimously: "You are a noble one, the son of a noble one." He announced to them his decision: "You may go free! No reproach this day shall be on you; may God forgive you."

A Mercy for Women

Prophet Muhammad (PBUH) was also very kind and affectionate towards women. Women were very badly treated in those times. The Noble Prophet gave them honor and dignity at par with men in the community. 'Umar reported: "We did not have much regard for women while we were at Makkah, but they were better treated in Madinah. Allah's Messenger established women's rights through his sayings and commandments, which improved their position and status."

A Mercy for Children

Allah's Messenger was particularly compassionate towards children. When he saw a child crying, he sat beside him or her and shared his or her feelings. He felt the pain of a mother for her child more than the mother herself. Once he said: "I stand in prayer and wish to prolong it. However, I hear the cry of a child and cut the prayer short for the anxiety which the mother is feeling." (Al-Bukhari)

He would take children in his arms and embrace them. He was once hugging his beloved grandsons, Hasan and Hussain, when Aqrah bin Haabis told him, 'I have got ten children. So far, I have not kissed any of them.' Allah's Messenger responded: "The one with no pity for others is not pitied." (Al-Bukhari and Muslim) According to another version, he said: "What can I do for you if Allah has removed from you the feeling of compassion?" (At-Tirmidhi)

A Mercy for Animals

His compassion encompassed not only human beings, but also animals.

The Prophet (PBUH) forbade his companions to keep the unintelligent creatures hungry or thirsty, to disturb or to overburden them. He commended that kindness and putting them at ease were meritorious acts tending to bring man nearer to Allah. Abu Hurairah reports the Prophet as saying: "A traveler who was thirsty saw a well in the way. He got inside the well and when he came out he saw a dog licking mud due to thirst. The man realized that the dog was as thirsty as him, so he got into the well again, filled his leather sock with water and carried it out holding it with his teeth. Thus, he quenched the thirst of the dog. Allah was pleased with this act of kindness and pardoned his sins." The Companions asked: "O Messenger of Allah is there recompense in the matter of beasts and wild animals also?" The Prophet replied: "There is recompense in regard to every creature that has a living heart."

'Abdullah bin 'Umar related that the Prophet said: "A woman was cast away to hell only because she had withheld food and water from her cat and refused to set it free so that the cat might satisfy its hunger by eating worms and insects."

Once on return from a military campaign, a few Companions took away the chicks of a bird from their nest to stroke them. The mother bird came back and when it could not find its chicks in the nest, it began to fly around screeching. When informed of the matter, Allah's Messenger became angry and ordered the chicks to be put back in the nest. (Abu Dawood)

Conclusion

The love and compassion of Allah's Messenger (PBUH) for all kinds of creatures was not of the kind claimed by today's 'humanists'. He was sincere and balanced in his love and compassion. He was more compassionate than any other person. He was a Prophet raised by Allah, the Creator and Sustainer of all beings, for the guidance and happiness of conscious beings - mankind and jinn - and the harmony of existence. Therefore, he lived not for himself but for others; he is a mercy for all the worlds.
