Is the manumission of an Umm Walad (a female slave who bore her master's child) valid?
General Chapter
Al-Mughni
Book of Zihar
Primary text
The manumission of an Umm Walad is invalid because the right to her manumission is established due to a cause other than expiation (kaffārah), and the ownership over her is incomplete, which is why selling her is impermissible.

Tāwūs and al-Battī permit the manumission of an Umm Walad, asserting that it is a valid manumission.
