Muwatta Imam Malik Book of Good Character, Hadith 11

Malik related to me from Ibn Shihab from Humayd ibn Abd ar-Rahman ibn Awf that a man came to the Messenger of Allah ﷺ and said, "Messenger of Allah, teach me some words which I can live by. Do not make them too much for me, lest I forget." The Messenger of Allah ﷺ said, "Do not be angry."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، أَنَّ رَجُلاً، أَتَى إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ عَلِّمْنِي كَلِمَاتٍ أَعِيشُ بِهِنَّ وَلاَ تُكْثِرْ عَلَىَّ فَأَنْسَى . فَقَالَ رَسُولُ اللَّهِ ﷺ " لاَ تَغْضَبْ " .
