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."

Sayyiduna Abu Hurayrah (may Allah be pleased with him) says: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever frees a believing slave, Allah Almighty will free, in return for every limb of it, a limb of his from Hellfire, even his private part in return for its private part."

Fatimah bint Ali narrates from her father (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever frees a Muslim or believing soul, Allah Almighty will protect, in return for each of its limbs, a limb of the one who freed it from the Fire."

It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever has a slave girl and teaches her good manners well and gives her the best education, then frees her and marries her, for him there are two rewards."
