حَدَّثَنَا مُحَمَّدُ بْنُ سَلامٍ، قَالَ: أَخْبَرَنَا مُحَمَّدُ بْنُ فُضَيْلِ بْنِ غَزْوَانَ، عَنْ لَيْثٍ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: ”عَلِّمُوا وَيَسِّرُوا وَلاَ تُعَسِّرُوا، وَإِذَا غَضِبَ أَحَدُكُمْ فَلْيَسْكُتْ.“
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Teach the people, deal with them gently and do not make things difficult. When any one of you becomes angry, he should remain silent."
