Messenger of Allah ﷺ said, "The strong is not the one who overcomes the people by his strength, but the strong is the one who controls himself while in anger." (Using translation from Bukhārī 6114)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَيْسَ الشَّدِيدُ بِالصُّرَعَةِ إِنَّمَا الشَّدِيدُ الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ» خَالَفَهُ شُعَيْبٌ وَمَعْمَرٌ  

[Machine] I heard the Prophet ﷺ and Nasr bin Ali bin Nasr informed us that Abdul A'la narrated to us from Ma'mar, from Az-Zuhri, from Humaid bin Abdul Rahman, from Abu Hurairah that the Prophet ﷺ said, "The strong person is not the one who can wrestle others. Rather, the strong person is the one who can control himself when he is angry."  

سَمِعْتُ النَّبِيَّ ﷺ وَأَخْبَرَنَا نَصْرُ بْنُ عَلِيِّ بْنِ نَصْرٍ عَنْ عَبْدِ الْأَعْلَى قَالَ حَدَّثَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي هُرَيْرَةَ أَنَّ النَّبِيَّ ﷺ قَالَ «لَيْسَ الشَّدِيدُ بِالصُّرَعَةِ» قَالُوا فَمَا الشَّدِيدُ؟ قَالَ «الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ»  

[Machine] The Messenger of Allah, ﷺ , said, "Indeed, the strong person is not the one who overpowers people, but the strong person is the one who controls himself."  

قَالَ رَسُولُ اللهِ ﷺ «إِنَّ الشَّدِيدَ لَيْسَ مَنْ غَلَبَ الرِّجَالَ وَلَكِنَّ الشَّدِيدَ مَنْ غَلَبَ نَفْسَهُ»
