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
