the freed slave of Ibn `Abbas, that Maimuna bint Al-Harith told him that she manumitted a slave-girl
without taking the permission of the Prophet. On the day when it was her turn to be with the Prophet,
she said, "Do you know, O Allah's Messenger (ﷺ), that I have manumitted my slave-girl?" He said, "Have
you really?" She replied in the affirmative. He said, "You would have got more reward if you had
given her (i.e. the slave-girl) to one of your maternal uncles."
Sahih al-Bukhari Book 51, Hadith 26
