Al-Adab Al-Mufrad, Book 8, Hadith 13 (In-Book) ⓘ

He reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Who do you reckon to be the one who most often throws people down (in a fight)?" They replied, "The one whom men do not throw down." He said, "No the one who throws people down is the person who controls himself when he is angry."

قَالَ‏:‏ وَقَالَ رَسُولُ اللهِ صلى الله عليه وسلم‏:‏ مَا تَعُدُّونَ فِيكُمُ الصُّرَعَةَ‏؟‏ قَالُوا‏:‏ هُوَ الَّذِي لاَ تَصْرَعُهُ الرِّجَالُ، فَقَالَ‏:‏ لاَ، وَلَكِنَّ الصُّرَعَةَ الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَبِ‏.‏
