Muwatta 2361

Malik said of a man who freed half of a slave while he was ill, and the manumission was made final for half of him, or for all of him, and he had conditionally freed another slave before that: the conditionally freed one is given priority over the one he freed while ill, because a man may not retract what he made conditional, nor countermand it with a matter that retracts it. When the conditionally freed slave is freed, what remains of the third goes to the one whose half he freed, until his manumission is completed in the third of the dead man's property. If the excess of the third does not reach that, a part of him equal to the excess is freed. ¹
