Hubayrah bin Yarim said that Sayyiduna al-Hasan bin Ali (may Allah be pleased with him) addressed the people and said: "O people! You have lost a man whom those before did not surpass, and whom those after will not attain. The Messenger of Allah (peace and blessings be upon him) used to send him with the army detachment, with Jibril on his right and Mika'il on his left. By Allah, he left behind no gold or silver except eight hundred dirhams, which were the price of a servant."
