Sunan Ibn Majah, Volume 5, Book 37, Hadith 4189 (DarusSalam) ⓘ
It was narrated from Ibn ‘Umar that the Messenger of Allah said: “There is no gulp that brings greater reward with Allah than a gulp of anger that a man swallows (suppresses), seeking thereby the Face of Allah.”
حَدَّثَنَا زَيْدُ بْنُ أَخْزَمَ، حَدَّثَنَا بِشْرُ بْنُ عُمَرَ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ يُونُسَ بْنِ عُبَيْدٍ، عَنِ الْحَسَنِ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَا مِنْ جُرْعَةٍ أَعْظَمُ أَجْرًا عِنْدَ اللَّهِ مِنْ جُرْعَةِ غَيْظٍ كَظَمَهَا عَبْدٌ ابْتِغَاءَ وَجْهِ اللَّهِ " .
