Mother of the Believers Sayyidah Maymunah (may Allah be pleased with her) said: I freed one of my slave-girls but did not ask permission of the Messenger of Allah (peace and blessings be upon him). When the day came on which he would visit her, she said: O Messenger of Allah! Do you know that I have freed such-and-such slave-girl of mine? He (peace and blessings be upon him) said: "Did you really?" She said: Yes. He (peace and blessings be upon him) said: "Had you given that slave-girl to your maternal uncles, you would have had a far greater reward for it."
