(30) باب فَضْلِ مَنْ يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ وَبِأَىِّ شَىْءٍ يَذْهَبُ الْغَضَبُ
Abu Huraira reported:
I heard Allah's Messenger (ﷺ) as saying: One is not strong because of one's wrestling skillfully. They said: Allah's Messenger, then who is strong? He said: He who controls his anger when he is in a fit of rage.
