His manners and disposition "By the grace of Allah, you are gentle towards the people; if you had been stern and ill-tempered, they would have dispersed from round about you" (translation of Qur'an 3:159) About himself the prophet (pbuh) said "Allah has sent me as an apostle so that I may demonstrate perfection of character, refinement of manners and loftiness of deportment." (Malik, Mawatta; Ahmed, Musnad; Mishkat) By nature he was gentle and kind hearted, always inclined to be gracious and to overlook the faults of others.
Politeness and courtesy, compassion and tenderness, simplicity and humility, sympathy and sincerity were some of the keynotes of his character. In the cause of right and justice he could be resolute and severe but more often than not, his severity was tempered with generosity. He had charming manners which won him the affection of his followers and secured their devotion. Though virtual king of Arabia and an apostle of Allah, he never assumed an air of superiority.
Not that he had to conceal any such vein by practice and artifice: with fear of Allah, sincere humility was ingrained in his heart.
He used to say, "I am a Prophet of Allah but I do not know what will be my end." (Bukhari, Sahih Bukhari, Chapter "Al-Janaiz") In one of his sermons calculated to instill the fear of Allah and the day of reckoning in the hearts of men, he said, "O people of Quraish be prepared for the hereafter, I cannot save you from the punishment of Allah; O Bani Abd Manaf, I cannot save you from Allah; O Abbas, son of Abdul Mutalib, I cannot protect you either; O Fatima, daughter of Muhammad, even you I cannot save." (Sahahin) He used to pray, "O Allah!
I am but a man. If I hurt any one in any manner, then forgive me and do not punish me." (Ahmed, Musnad, Vol. 6 pg. 103) He always received people with courtesy and showed respect to older people and stated: "To honor an old man is to show respect to Allah." He would not deny courtesy even to wicked persons. It is stated that a person came to his house and asked permission for admission. The prophet (pbuh) remarked that he was not a good person but might be admitted.
When he came in and while he remained in the house, he was shown full courtesy.
