SELF CONTROL H 45 "The person who is strong is not the one who knocks others out fighting; the one who is strong is the person who controls himself when he is angry." R 45 Muslim with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
45- وعن أبي هريرةَ رضي الله عنه أنّ رسولَ الله صلى الله عليه وآله وسلم ، قَالَ : "لَيْسَ الشَّدِيدُ بالصُّرَعَةِ ، إنَّمَا الشَدِيدُ الَّذِي يَملكُ نَفْسَهُ عِنْدَ الغَضَبِ" مُتَّفَقٌ عَلَيهِ . " وَالصُّرَعَةُ" : بضَمِّ الصَّادِ وَفَتْحِ الرَّاءِ وأَصْلُهُ عِنْدَ العَرَبِ مَنْ يَصْرَعُ النَّاسَ كَثيراً .
