This article studies tombstones from eighth- to tenth- century CE Egypt that are designed to mark the grave of a Muslim slave. These funerary inscriptions are unusual in that they do not marginalize the enslaved as much as do other early Islamic sources. Furthermore, they reveal otherwise undocumented attitudes towards persons who died as slaves. Offering a thick description of an unpublished tombstone for a ninth-century concubine-mother (umm walad), the present article analyses tombstones for slaves from two perspectives. It first studies the representation of the enslaved and the specific terminology that tombstones used to designate the deceased as enslaved. It then turns to the commemorative context of tombstones, arguing that tombstones of slaves served similar purposes and used similar illocutionary strategies to those used by contemporary tombstones for free Muslims. Despite these similarities between tombstones of free and enslaved persons, we see that deceased slaves were commemorated as members of the Muslim community as well as the legal property of their owners.
