Does a person who is partially a slave (partially free) have custody?

Primary text

If there is no predetermined schedule (*muhayā'ah*) between the part-owner (master) and the partially free person, then the partially free person has no custody because they cannot fully exercise it, as their benefits are shared with their master. If there is a schedule (*muhayā'ah*), then according to the قياس (analogy) of Ahmad's opinion, the partially free person has custody during their allotted time because Ahmad stated that for anything divisible, they are entitled to half of everything. This is the preferred view of Abu Bakr.
