It is narrated from Qais: When Muawiyah and Amr came to Kufa, Harith bin Azma came to Amr. Amr was about to leave on horseback when Harith said to him, "I had come for a task; if you were seated, I would have asked you a question." Hazrat Amr replied, "Ask whatever question you have, for the answer I can give you while seated, I can give you now as well." Harith said, "Tell me something about Ali (may Allah be pleased with him) and Uthman." He replied, "Anger and selfishness had gathered together in one place, so anger overcame selfishness." Then he went on his way.
