another person, following the hadith of Jābir, who sold his camel to the Prophet, peace and blessings be upon him, while reserving the right to ride it to Medina.

He also permits someone who frees a slave to reserve the slave’s service for the slave’s lifetime, the master’s lifetime, or another period. This follows the hadith of Safīnah, whom Umm Salamah freed on condition that he serve the Prophet, peace and blessings be upon him, for as long as he lived.

According to most of Ahmad’s reported positions, a man may also free his slave woman and make her emancipation her dowry, as in the hadith of Safiyyah, and as Anas ibn Mālik and others did—even without the woman’s consent. It is as though he freed her while reserving the right to sexual relations with her. However, he reserves that right through marriage, since reserving it without marriage is impermissible, unlike reserving her service.

He also permits someone establishing an endowment to reserve all its benefits and revenue for himself throughout his lifetime, as the Companions are reported to have done. A report on this has also been attributed directly to the Prophet, peace and blessings be upon him, by a Successor. As for whether a person may establish an endowment for himself, two positions are transmitted from Ahmad.

By analogy with his position, it is also permissible to reserve some of the benefit of property transferred as a gift, a dowry, compensation for a wife’s release from marriage, or a settlement in lieu of retribution, and in other similar ways of relinquishing ownership. This applies whether ownership is extinguished, as in emancipation, or transferred to another, whether for consideration, as in a sale, or without consideration, as in a gift.
