Prophet Muhammad’s Character

It is mentioned in the lengthy story about Sa’d ibn Hishaam ibn ‘Aamir, when he came to Madeenah and went to ‘Aa’ishah (may Allaah be pleased with her) and asked her about some matters. He said: I said: O Mother of the believers, tell me about the character of the Messenger of Allaah (peace be upon him). She said: Do you not read the Qur’aan? I said: Of course. She said: The character of the Prophet of Allaah (pbuh) was the Qur’aan. I wanted to get up and not ask about anything else until I died… Narrated by Muslim (746).
According to another report:
I said: O Mother of the believers, tell me about the character of the Messenger of Allaah (peace and blessings of Allaah be upon him). She said: O my son, do you not read the Qur’aan? Allaah says (interpretation of the meaning): “And verily, you (Oh Muhammad, peace and blessings of Allaah be upon him) are on an exalted (standard of) character” [Quran- al-Qalam 68:4].
The character of Muhammad was the Qur’aan. Narrated by Abu Ya’la (8/275) authentic narration

Al-Nawawi (may Allaah have mercy on him) said in Sharh Muslim (3/268):
What this means is that he acted in accordance with it, adhering to its limits, following its etiquette, paying heed to its lessons and parables, pondering its meanings and reciting it properly.

Allaah, may He be exalted, said (interpretation of the meaning): “And by the Mercy of Allaah, you dealt with them gently. And had you been severe and harsh hearted, they would have broken away from about you” [Aal ‘Imraan 3:159]. Allaah bestowed upon him the best attitude and conduct, and the best way of dealing with people and situations, even though he was illiterate and could neither read nor write. He grew up poor in an ignorant desert land, tending sheep, an orphan with neither father nor mother. But Allaah taught him all good characteristics and good ways, and taught him the stories of earlier and later generations, and that which brings success and salvation in the Hereafter and happiness in this world.
