THE REWARD FOR CONTROLLING OF ONE'S ANGER H 47 "The one who, in spite of having the capacity to avenge (a wrong) controls his anger, will be singled out and called by Allah, the Holy, the Exalted, above the multitude on the Day of Judgement and is given his choice of black-eyed houris, (the virgins of Paradise)." R 47 Abu Daud and Tirmidhi with a chain up to Mu'az son of Anas who related that the Prophet, praise and peace be upon him, said this.
47- وعن معاذِ بنِ أَنسٍ رضي الله عنه : أنَّ النَّبيَّ صلى الله عليه وآله وسلم ، قَالَ : "مَنْ كَظَمَ غَيظاً ، وَهُوَ قَادِرٌ عَلَى أنْ يُنْفِذَهُ ، دَعَاهُ اللهُ سُبحَانَهُ وَتَعَالى عَلَى رُؤُوسِ الخَلائِقِ يَومَ القِيامَةِ حَتَّى يُخَيِّرَهُ مِنَ الحُورِ العِينِ مَا شَاءَ" رواه أَبو داود والترمذي ، وَقالَ : "حديث حسن" .
