Abu Dawud Book 12, Hadith Number 2885.
Narated By Jabir ibn Abdullah : We went out with the Apostle of Allah (PBUH) and came to a woman of the Ansar in al-Aswaf. The woman brought her two daughters, and said: Apostle of Allah, these are the daughters of Thabit ibn Qays who was killed as a martyr when he was with you at the battle of Uhud, their paternal uncle has taken all their property and inheritance, and he has not left anything for them. What do you think, Apostle of Allah? They cannot be married unless they have some property. The Apostle of Allah (PBUH) said: Allah will decide regarding the matter. Then the verse of Surat an-Nisa was revealed: “Allah (thus) directs you as regards your children’s (inheritance).” Apostle of Allah (PBUH) said: Call to me the woman and her husband’s brother. He then said to their paternal uncle: Give them two-thirds and their mother an eighth, and what remains is yours.
Abu Dawud said: The narrator Bishr made a mistake. They were the daughters of Sa’d b. al-Rabi’ for Thabit b. Qais was killed in the battle of Yammamah.
