Hazrat Asim bin Damrah (may Allah have mercy on him) narrates: When Hazrat Ali (may Allah be pleased with him) was martyred, Hazrat Hasan bin Ali (may Allah be pleased with him) delivered a sermon in which he said: O people of Kufa, or he said: O people of Iraq! Indeed, there was a man among you who was martyred at night, or he said: who passed away today. Those before him did not surpass him in knowledge, nor will those after him attain his knowledge. Whenever the Noble Prophet (peace and blessings be upon him) sent him in any army, Hazrat Jibreel (peace be upon him) would be on his right side and Hazrat Mikaeel (peace be upon him) on his left side. Thus, that person would not return until Allah Almighty granted him victory.
