It is narrated by Hadrat Aishah (Radi Allaahu Ta’ala Anha) that the Prophet was never harsh in speech neither by habit nor by intention. He never spoke unbecomingly even in the market place. He never requited evil with evil; on the contrary, he always forgave. Because of modesty he never fixed his gaze on any one’s face. If he ever found it necessary to speak about any thing unbecoming, he always expressed himself allusively.
Hadrat Ali (Radi Allaahu Ta’ala Anhu) narrated that he was extremely open-hearted, truthful in speech and gentle in nature. In social intercourse he was most gracious. If any one asked him to meals he always accepted the invitation. He never refused a present even if it was no more than the trotters of a cow or goat, and made it a point to give something in return for the present. He always accepted an invitation no matter whether it came from a free man or a bondman or a bondwoman, or a poor man. He visited every sick person even in the outermost part of Madina. He accepted the plea of any one apologizing to him; sometimes he spread his own cloak to seat the guest; often he left his own cushion and pillow for his guest. He never interrupted others. He was un-excelled in smiling and cheerfulness of dispositions, except when receiving a revelation or delivering sermon or speech (when, of course, he was in ecstasy, which was no occasion for smiling or the manifestation of cheerfulness).
