Hisham bin Urwah narrates from his father, and he from Sayyidah Safiyyah bint Abdul Muttalib (may Allah be pleased with her). Urwah heard her say: "I am the first woman who killed a man. I was in Hassan bin Thabit's fortress 'Fari'', and when the Prophet (peace and blessings be upon him) dug the trench, Hassan (may Allah be pleased with him) was with us among the women and children." Sayyidah Safiyyah (may Allah be pleased with her) related: "A Jew passed by us and began circling the fortress, so I said to Hassan: 'This Jew is circling the fortress, as you can see, and I fear that he will inform (the enemy) of our weak points, while the Messenger of Allah (peace and blessings be upon him) and his Companions are occupied (in battle); so get up and kill him.'" Hassan (may Allah be pleased with him) replied: "O daughter of Abdul Muttalib! May Allah forgive you. By Allah! You know that I am not the man for this task." Sayyidah Safiyyah says: "When he said that and I saw no (means of defence) in him, I tightened my waist-wrapper, took up a post of the fortress, went down, and struck that Jew with it again and again until I killed him. Then I came back into the fortress and said: 'O Hassan! Go down and strip him of his belongings (as spoils); nothing prevented me from stripping him except that he was a strange man.'" He said: "I have no need of his belongings." This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but the two Shaykhs did not record it. An account of Sayyidah Arwa bint Abdul Muttalib, the paternal aunt of the Messenger of Allah (peace and blessings be upon him); I have not found mention of her acceptance of Islam anywhere except in the book of Abu Abdullah al-Waqidi.
