184/245 عن ابن عباس قالَ : قالَ رسول الله صلى الله عليه وسلم : " علموا، ويسروا [علموا ويسروا(ثلاث مرات)/1320]، ولا تعسروا، وإذا غضب أحدكم فليسكت[مرتين]".
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both), he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Teach and make things easy," he said this three times. "And do not make things difficult, and when any one of you becomes angry, he should remain silent," he said this two times.
