Hafs bin Khalid narrates from his father, from his grandfather, that when Sayyiduna Ali (may Allah be pleased with him) was killed, Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both) stood up, praised and extolled Allah, and then said: "To proceed: By Allah, tonight you have killed a man who was martyred on the night in which the Qur'an was revealed; on this night Yusha' bin Nun, the companion of Musa (peace be upon him), was killed, and on this night Isa son of Maryam (peace be upon them both) was raised up. No one before him surpassed him, and no one after him reached his rank. When the Messenger of Allah (peace and blessings be upon him) sent him on a military expedition (sariyyah), Jibril (peace be upon him) would be on his right and Mika'il (peace be upon him) on his left. By Allah, he left behind neither gold nor silver, except seven hundred or eight hundred dirhams which he had set aside to buy a servant."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Hafs bin Khalid except Sukayn bin Abd al-Aziz, and Abd al-Rahman is alone in narrating it."
