“Indeed, in this [Quran] is notification for a worshipping people. And We have not sent
you, [O Muhammad], except as a mercy to the worlds.” [Quran: 21:106-107]
Allaah's Messenger 
was the kindest of men in the same way as he excelled all others in courage and valour. Being extremely kind-hearted, his
eyes brimmed with tears at the slightest sign of inhumanity. A Companion, Shaddaad bin 'Aws 
reported the Apostle as saying: "Allaah has commanded you to show kindness to everyone, so
if you have to kill, kill in a good manner, and if you slaughter an animal, slaughter it gently. If anyone of you has to slay
an animal, he should sharpen the blade first and treat the animal well." Ibn 'Abbaas relates that a man threw a goat on its side and then started sharpening his knife. When the Prophet saw him he said: "Do you want to kill it twice? Why did you not
sharpen the knife before throwing it on the ground?"
A Mercy for the Believers
The Messenger’s 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 Allaah’s Messenger visited him in his house. On seeing his faithful Companion in a pitiful state, he was moved to tears. Then, he said:
“Allaah does not punish because of tears, nor because of grief, but
he punishes because of this."- and he pointed to his tongue. [Al-Bukhaari]
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 . 'Umar one the Prophet’s 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 replied: “Were I to do this, Allaah would disfigure me on the Day
of Judgement, despite the fact that I am His messenger.”
In Makkah, his people inflicted him with every kind of suffering,
eventually forcing him to emigrate to Madeenah, 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 was also very kind and affectionate towards women. Women were very badly treated in those times. The Noble Prophet gave them honour 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 Madeenah. Allaah's
Messenger established women's rights through his sayings and commandments, which improved their position and status."
A Mercy for Children
Allaah’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-Bukhaari]
He would take children in his arms and embrace them. He was once hugging his beloved grandsons, Hasan and Husayn, when
Aqrah bin Haabis told him, ‘I have got ten children. So far, I have not kissed any of them.’ Allaah’s Messenger
responded: “The one with no pity for others is not pitied.” [Al-Bukhaari
and Muslim]
According to another version, he said: “What
can I do for you if Allaah has removed from you the feeling of compassion?” [At-Tirmithi]
A Mercy for Slaves
The Prophet strongly enjoined the duty of kind and generous treatment upon slaves, servants and labourers engaged in manual work. Jaabir
related the Apostle of Allaah as saying: "Feed them with the food which you eat, clothe them with such clothing as you wear,
and do not cause trouble to Allaah's creatures." The Apostle is further stated to have said: "Those whom Allaah has made your dependents are
your brothers, servants and helpmates. Anybody whose brother has been made subservient to him ought to feed him with the food
he eats and clothe him with the clothes he wears; command him not to do that which he is unable to do and if it becomes necessary
to do so then he should help him in doing the job."
A Mercy for Animals
His compassion encompassed not only human beings, but also animals.
The Prophet 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 Allaah. Abu Hurayrah reports the Prophet as saying: "A traveller 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 realised 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. Allaah was pleased with this act of kindness and pardoned his sins." The Companions asked: "O Messenger
of Allaah, 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."
'Abdullaah 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, Allaah’s Messenger became angry and ordered the chicks to be put back in the nest. [Abu Daawood]
Conclusion
The love and compassion of Allaah’s Messenger 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 Allaah, 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.
