Musnad Ahmad Hadith 14798

It is narrated from Jabir (may Allah be pleased with him) that the wife of Sa'd bin Rabi' came to the Prophet (peace and blessings of Allah be upon him) with her two daughters who were from Sa'd, and said, "O Messenger of Allah! These are the two daughters of Sa'd. Their father was martyred with you in the Battle of Uhud. Their uncle has taken possession of their wealth and has not left anything for them. Now they can only get married if they have some wealth." The Prophet (peace and blessings of Allah be upon him) said, "Allah will decide about this matter." Then the verse of inheritance was revealed, and the Prophet (peace and blessings of Allah be upon him) called their uncle and said, "Give two-thirds to Sa'd's two daughters and one-eighth to their mother. Whatever remains after that is yours."
