It is narrated from Hubayrah, he says: Sayyiduna Hasan bin Ali (peace be upon him) delivered a sermon to us and said: Yesterday, a man departed from you who, in terms of knowledge, was not surpassed by anyone among the earlier people, nor will anyone among the later ones attain his rank. Whenever the Messenger of Allah (peace and blessings be upon him) sent him forth with a flag, Jibreel (peace be upon him) would be on his right side and Mikaeel (peace be upon him) on his left side, and he would not return without achieving victory.
