Is the *Umm Walad* (mother of the master's child) guaranteed for wrongful seizure (Ghasb)?

Primary text

The *Umm Walad* is guaranteed for wrongful seizure. This position is held by Al-Shafi'i, Abu Yusuf, and Muhammad. The basis for this ruling is that anything guaranteed for its value is guaranteed upon wrongful seizure, analogous to a slave (*Qinn*). Furthermore, since the *Umm Walad* is owned property, she is analogous to a *Muddabarah* (a slave designated for manumission upon the master's death), whereas a free woman is neither owned property nor is she guaranteed for her value.
