Musannaf Ibn Abi Shayba 26:405

Narrated to us Abd al-A’la, from Hisham, from Muhammad, that a woman from the Ansar emancipated Salim as a *sa’ibah* (a type of manumission where the master relinquishes all rights of inheritance). Then she said to him, "Ally yourself with whomever you wish." So he allied himself with Abu Hudhayfah ibn Utbah. He was killed on the day of al-Yamamah, so his wealth was given to the woman who had emancipated him.
