Musannaf Ibn Abi Shaybah 13052 — The reward for freeing a slave

Shurahbil bin al-Simt says: We said to Sayyiduna Ka'b bin Murrah (may Allah be pleased with him): "O Ka'b bin Murrah, narrate to us a hadith from the Messenger of Allah (peace and blessings be upon him), and be careful." He said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever frees a Muslim man, he will be his ransom from the Fire; each bone of the freed man will suffice for a bone of his. And whoever frees two Muslim women, they will both be his ransom and shield from the Fire; every two bones of theirs will suffice for one bone of his."
