AVOIDANCE OF ANGER H H 48 "Someone asked the Prophet, praise and peace be upon him, for advice. So he advised: 'Do not give way to anger.' The man repeated his request several times, and each time the Prophet, praise and peace be upon him, said the same: 'Do not give way to anger.'" R 48 Bukhari with a chain up to Abu Hurairah who related this.
48- وعن أبي هريرةَ رضي الله عنه : أنَّ رَجُلاً قَالَ للنبي صلى الله عليه وآله وسلم : أوصِني . قَالَ : "لا تَغْضَبْ" فَرَدَّدَ مِراراً ، قَالَ : "لاَ تَغْضَبْ" رواه البخاري .
