Ubaydullah bin Abi Ja'far narrates from the Messenger of Allah (peace and blessings be upon him) that the Messenger of Allah (peace and blessings be upon him) said to Umm Ibrahim: "Your child has set you free."
This is munqati' (its chain is broken).
Sayyidah Aishah (may Allah be pleased with her) said that when the Prophet (peace and blessings be upon him) passed away, he did not leave behind any dirham or dinar, nor any male or female slave.
