The Prophet salla Allahu alayhi wasallam usually seemed cheerful, and he liked to smile. Even when others were rude to him, he was never harsh and rude. He never raised his voice in the market place.
If faced with a choice between two options, the Prophet salla Allahu alayhi wasallam would always choose the easier one, provided that it did not lead to sin. Above everything else, he avoided sinning or anything leading to disobedience of Allah. He never sought revenge for any offense committed against himself, but when the honor of Allah was at stake, he would certainly punish the offender.
As we have seen over the course of the events in his life, the Prophet salla Allahu alayhi wasallam was generous, brave, strong and extraordinarily patient. Never vulgar or obscene, his dislike of something was apparent in his face. He never stared directly at anyone, nor did he ever glare at anyone in displeasure. He never rebuked his servant, nor was he ever heard saying something unkind about anyone.
Even before his appointment as Allah’s Messenger, the Prophet salla Allahu alayhi wasallam was known as “Al-Ameen” (the Trustworthy). He always kept his promises, and remained humble even in victory. He respected the ties of kinship, attending the funerals of his relatives and Companions. He sat with the poor and needy, and accepted invitations extended to him from slaves. At the height of his power as head of the Islamic state, he lived modestly. He never attempted to outdo others in serving rich food or wearing expensive clothing.
