Praise be to Allah and may Allah increase the honour and raise the rank of our Master Muhammad sallallahu ^alayhi wa sallam.
Allah said in the Honourable Qur’an:

(وَلَكِن رَّسولَ اللهِ وَخَاتَمَ النَّبِيِّينَ)
This verse means that Muhammad was the last of the messengers and the prophets sallallahu ^alayhi wa sallam.

He is Muhammad, whom Allah has given the best manners that were strongly emphasised in the Qur’an. He is Muhammad who accepts what the Honourable Qur’an calls to accept and abided by its orders, he followed the manners and conducts that the Qur’an calls for. He would not take revenge on anyone; however, when the boundaries of the Religion were violated he used to get very angry.

He is Muhammad whom Allah, the Merciful, has sent as a mercy to this nation. He is Muhammad, the most courageous of all men when confronting the enemy. He is Muhammad, who has never said “No” whenever asked to give away any permissible worldly thing unless he could not find. He is Muhammad, the most truthful human when talking and the most trustworthy person when dealing with.

Allah the Exalted gave His Prophet sallallahu ^alayhi wa sallam the highest rank of the good manners.
 
When silent, he used to look to the ground more than looking to the sky; however, when talking he used to direct his sight to the sky as an indication that it is the Qiblah of du^a’ (direction for supplication) and the place from which mercies, blessings, and Revelations descended. He never focused his eyes in anybody’s face out of his extreme modesty and humbleness.

Prophet Muhammad was the most humble person; he would not extend his feet while sitting with people out of respect.
He was very merciful and his mercy was not restricted to the human beings, rather, his mercy included the animals and birds as well. If a cat, for example, would come to him he would lower the pot to make it easier for it to drink.
He is Muhammad, who out of humbleness used to sit with the poor, the needy and even the slaves. He never treated anyone with insolence.
Verse 4 of Surat al-Qalam clarified his manners:

{وإِنَّكَ لَعَلَى خُلُقٍ عَظِيمٍ}
It means: “Verily, your manners are distinguished and great.”

When Lady ^A’ishah may Allah raise her rank was asked about the Prophet’s manners, she said: {كان خلقه القرءان}
It means: “His manners were all what the Qur’an ordered to do.”

On another occasion when ^A’ishah may Allah raise her rank was asked about the Prophet’s manners, she said: “He was moderate but not sinful, he never used to spend his time during the day in the market places with the purpose of collecting money. He never mistreated those who mistreated him; but rather, he used to pardon and forgive.”

As for the news about his generosity, they are plenty; among them is what Imam Muslim related from the route of Anas that he said: “The Messenger of Allah sallallahu ^alayhi wa sallam used to give anything that would benefit Islam if he was to be asked. Once a man came to him asking for some support, the Prophet sallallahu ^alayhi wa sallam gave him sheep which were grazing between two mountains. That man went to his people and said: “O people embrace Islam, for Muhammad gives as much as the one who does not fear poverty.” 

As for his humbleness, it was related by al-Bayhaqiyy, at-Tirmidhiyy, and Ibn Majah from the route of ^Abdullah who said: The Prophet sallallahu ^alayhi wa sallam lay down on a mat, which left some marks on his skin. So I began stroking my hand over his skin so that the marks would disappear and said: O Messenger of Allah, please give us permission to put something on the floor for you to sleep on without leaving such marks on your body?

The Prophet replied: “Keep the worldly pleasures away from me, and keep me away from them, for the lifespan of one in this world goes so fast that it is similar to the time a riding person would spend to rest in a shade under a tree after which he has to leave and continue his journey.”

He, may Allah raise his rank, was attributed with good traits such as truthfulness, honesty, keeping ties with his kin, chastity, generosity, bravery, and obeying Allah in all instances; moments; and with every breath. This was along with splendid eloquence, complete advice, compassion and mercy, benevolence, and treating the poor, the orphans, the widows, and the weak ones kindly. Muhammad, may Allah raise his rank, is the most humble human; he looked after the needy; attended their funerals and visited the sick. The Prophet was very handsome and of a great lineage.
We humbly ask Allah to guide us to the right path and to make us die as pious Muslims.

And Allah knows best.
