Hadith 27510

Malik said about a man who had his slave in a kitaba and then themukatab died and left his umm walad, and there remained for him someof his kitaba to pay and he left what would pay it, "The umm walad isa slave since the mukatab was not freed until he died and he did notleave children that were set free by his paying what remained, so thatthe umm walad of their father was freed by their being set free."Malik said about a mukatab who set free a slave of his or gavesadaqa with some of his property and his master did not know thatuntil he had set the mukatab free, "That has been performed by him andthe master does not rescind it. If the master of the mukatab knowsbefore he sets the mukatab free, he can reject that and not permit it.If the mukatab is then freed and it becomes in his power to do so, hedoes not have to free the slave, nor give the sadaqa unless he does itvoluntarily from himself."
