Mishkat al-Masabih 29 Excellent Qualities and Description of the Prophet كتاب الفضائل والشمائل 80

وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: لَمْ يَكُنْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاحِشًا وَلَا مُتَفَحِّشًا وَلَا سَخَّابًا فِي الْأَسْوَاقِ وَلَا يَجْزِي بِالسَّيِّئَةِ السَّيِّئَةَ وَلَكِنْ يَعْفُو وَيَصْفَحُ. رَوَاهُ التِّرْمِذِيّ

`A’isha said God’s messenger was not unseemly or lewd in his language, nor was he loud-voiced in the streets, nor did he return evil for evil, but he would forgive and pardon. Tirmidhi transmitted it.
