PROPHET MUHAMMAD'S KINDNESS
Prophet Muhammad ﷺ was as kind as he was polite. He always treated people with kindness and tenderness and never showed harshness even to his enemies. The people who abused him, threw thorny bushes and stones and dirt on him and were thirsty for his blood, received nothing but kindness from him. He showed kindness to all, irrespective of whether they were friends or foes.The kind and gentle nature of Prophet Muhammad ﷺ endeared him to all, young and old, rich and poor, men and women.
In his boyhood, he never fought or quarrelled with anyone like other boys of his own age, but always showed kindness and friendship, to the aged as well as to the young. When he reached maturity, he was well-known for his kindness and sympathy to the poor orphans and widows. After he became the Prophet ﷺ, his kindness to people knew no bounds. Anas said, "I served Allah's Messenger for ten years and he never said to me, 'shame' or 'why did you do such a thin"?' or 'why did you not do such and such a thing?' " In Medinah, when he was the head of the state and had the power to take revenge on his enemies, he treated all captives and prisoners-of-war, including his hard-core enemies, very kindly.
Allah mentions this quality of Muhammad's in the Qur'an, "O Messenger, it is a great Mercy of God that you are very gentle and lenient towards them; for, had you been harsh and hardhearted, they would all have broken away from you." Qur'an Surah Al’e Imran 3:159 
The Prophet’s love for children was not restricted to his children and grandchildren but above any cast, creed or color. The scope of his mercy and affection embraced all children, and he showed the same interest and gentleness to other children. Usamah ibn Zaid (may Allah be pleased with him) narrates: Allah’s Messengerﷺ used to put me on (one of) his thighs and put Al-Hasan ibn `Ali on his other thigh, and then embrace us and say, “O Allah! Please be merciful to them, as I am merciful to them.” Sahih Al Bukhari 6003(Vol. 8: 32)
The Prophet صلی اللہ علیہ وسلم was always concerned about everyone’s thought and feeling. The following hadith narrated by Anas ibn Malik (may Allah be pleased with him) proves his thoughtful character: The Prophet صلی اللہ علیہ وسلم said, “(It happens that) I start the prayer intending to prolong it, but on hearing the cries of a child, I shorten the prayer because I know that the cries of the child will incite its mother’s passions.” Sahih al-Bukhari 709 (Vol1:677)
The Prophet ﷺ enjoined upon Muslims to treat the poor kindly and to help them with alms, zakaat, and in other ways. He said: "He is not a perfect Muslim who eats his fill and lets his neighbor go hungry." He asked: "Do you love your Creator? Then love your fellow beings first."
Monopoly is unlawful in Islam and he preached that: "It is difficult for a man laden with riches to climb the steep path that leads to bliss."
He did not prohibit or discourage the acquisition of wealth but insisted that it be lawfully acquired by honest means and that a portion of it would go to the poor. He advised his followers: "To give the laborer his wages before his perspiration dried up." Ibn Majah Vol. 3: 2443
He did not encourage beggary either and stated that: "Allaah is gracious to him who earns his living by his own labor, and that if a man begs to increase his property, Allah will diminish it and whoever has food for the day, it is prohibited for him to beg."
To his wife he said: "O 'Aa'ishah, love the poor and let them come to you and Allaah will draw you near to Himself."[Al-Bukhaari]
One or two instances of the Prophet's concern for the poor may be given here. A man from Madeenah, Ibaad Ibn Sharjil, was once starving. He entered an orchard and picked some fruit. The owner of the orchard gave him a sound beating and stripped off his clothes. The poor man appealed to the Prophet who remonstrated the owner thus: "This man was ignorant, you should have dispelled his ignorance; he was hungry, you should have fed him." His clothes were restored and, in addition, some grain was given to him. [Abu Daawood]
A debtor, Jaabir Ibn Abdullaah was being harassed by his creditor as he could not clear his debt owing to the failure of his date crop. The Prophet ﷺ went with Jaabir to the house of the creditor and pleaded with him to give Jaabir some more time but the creditor was not prepared to oblige. The Prophet then went to the oasis and having seen for himself that the crop was really poor, he again approached the creditor with no better result. He then rested for some time and approached the creditor for a third time but the latter was adamant. The Prophet went again to the orchard and asked Jaabir to pluck the dates. As Allaah would have it, the collection not only sufficed to clear the dues but left something to spare. Sahih Al-Bukhaari 2395 (Vol.3:580)
The Prophetﷺnot only preached to the people to show kindness to each other but also to all living souls. He forbade the practice of cutting tails and manes of horses, of branding animals at any soft spot, and of keeping horses saddled unnecessarily. Sahih Muslim 2118(Book 24, Hadith 5284)
Narrated Salim: that Ibn `Umar disliked the branding of animals on the face. Ibn `Umar said, "The Prophet (ﷺ) forbade beating (animals) on the face." Sahih al-Bukhari 5541 (Vol. 7, Book 67, Hadith 449)
If he saw any animal over-loaded or ill-fed he would pull up the owner and say: "Fear Allaah in your treatment of animals."Sunan Abi Dawud 2548 (Book 14, Hadith 2542)
A companion came to him with the young ones of a bird in his sheet and said that the mother bird had hovered over them all along. He was directed by the Prophet to replace her offspring in the same bush. Sunan Abu Daawood 2675 (Book 14, Hadith 2669)
During a journey, somebody picked up some birds eggs. The bird's painful note and fluttering attracted the attention of the Prophet ﷺ who asked the man to replace the eggs. Al-Adab Al-Mufrad 382
As his army marched towards Makkah to conquer it, they passed a female dog with puppies. The Prophet not only gave orders that they should not be disturbed, but posted a man to see that this was done. He stated: "Verily, there is heavenly reward for every act of kindness done to a living animal." Sahih Al Bukhari 2466 (Vol.3: 646)
