It is narrated from Sayyidah Safiyyah bint Abd al-Muttalib (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) set out for the Battle of Uhud, he (peace and blessings be upon him) placed his pure wives in a fortified house called "Fari'", and he also placed Sayyiduna Hassan bin Thabit (may Allah be pleased with him) with them. Hassan (may Allah be pleased with him) kept looking out towards the Prophet (peace and blessings be upon him); when he pressed hard against the polytheists, he would exert himself along with him (peace and blessings be upon him) from inside the fort, and when he (peace and blessings be upon him) drew back, he too would turn back behind him (peace and blessings be upon him). Then some people from the Jews came, and one of them climbed up the fort until he was looking down on us. I said to Hassan (may Allah be pleased with him): "Get up and kill him." He said: "That is not within my power; had it been in me, I would have been with the Prophet (peace and blessings be upon him) (on the battlefield)." Sayyidah Safiyyah (may Allah be pleased with her) says: "Then I struck at his head until I cut it off. When I had cut it off, I said: 'O Hassan! Get up, take his head and throw it at those people,' while they were below the fort. He said: 'By Allah! That is not within my power.' So I picked up his head myself and threw it at them. They said: 'By Allah! We now know that Muhammad (peace and blessings be upon him) does not leave his family unprotected in such a way that no one is with them.' And they dispersed." Sayyidah Safiyyah (may Allah be pleased with her) narrated: "Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him) passed by us, and there was yellowness on him, as though he had been married shortly before that, and he was reciting rajaz verses:
'Wait a little, Hamal (a man of that name) will join the battle too; there is no harm in death when the appointed time has come.'"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyidah Safiyyah (may Allah be pleased with her) only with this chain."
"Ishaq bin Muhammad al-Farwi is alone in narrating it."
