It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The best of my Ummah are those of quick temper (with a sense of honour) who, when they become angry, return (to what is right)."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Ali (may Allah be pleased with him) only with this chain; Muhammad bin Uthman al-Farra' is alone in narrating it."
