Musannaf Ibn Abi Shaybah 12627 — A slave born of zina: does he suffice

Sa'id bin Abi Sa'id said: A woman came to Sayyiduna Abu Hurayrah (may Allah be pleased with him) and asked: "I have the son of a slave-girl who is not of legitimate birth, and I am obliged to free a slave. Will freeing him suffice?" He said: "Yes."
