The Messenger of Allah (ﷺ) sold a Mudabbar.

“A man among us promised freedom to a slave after his death, and he did not have any property other than him (this slave). So the Prophet (ﷺ) sold him, and Ibn (Nahham), a man from Banu 'Adi, bought him.”

The Prophet (ﷺ) said: “The Mudabbar is part of the one third of the estate.”

The Messenger of Allah (ﷺ) said: “Any man whose slave won an bears him a child, she will be free after he dies.”

“Mention was made of the mother of Ibrahim in the presence of the Messenger of Allah (ﷺ), and he said: 'Her son set her free.'”

Jabir bin `Abdullah رضی اللہ عنہما was heard to say: “We used to sell our slave women and the mothers of our children (Umahat Awaldina) when the Prophet (ﷺ) was still living among us, and we did not see anything wrong with that.”

The Messenger of Allah (ﷺ) said "Three who's support is a right upon Allah: the warrior in the path of Allah, the mukatab seeking to fulfill (his manumission debt), and the one getting married seeking chastity."

The Messenger of Allah (ﷺ) said: “Any slave who has made a contract to buy his freedom for one hundred Uqiyyah and pays it all except ten Uqiyyah; he is still a slave.” (One Uqiyyah is equal to 40 Dirham.)

The Prophet (ﷺ) said: “If anyone of you (women) has a Mukatab, and he has enough (wealth) to pay off (his contact of manumission), she must veil herself from him.”

Barirah رضی اللہ عنہا came to her when she was came to her when she was Muktabah, and her masters had written a contract of manumission for nine Uqiyyah. She (`Aishah) said: “If your masters wish I will pay them that in one sum, and the right of inheritance will belong to me.” He said: “So she went to her masters and told them about that, but they insisted that the right of inheritance should belong to them. `Aishah رضی اللہ عنہا mentioned that to the Prophet (ﷺ) and he said: 'Do it.' Then the Prophet (ﷺ) stood up and addressed the people. He praised and glorified Allah (SWT), then he said: 'What is the matter with some people who stipulated conditions that are not in the Book of Allah (SWT)? Every conditions that is not in the Book of Allah (SWT) is invalid, even if there are one hundred conditions. The Book of Allah(SWT) is more deserving of being followed and the conditions of Allah (SWT) are more binding. And the Wala belongs to the one who manumits (the slave).”

I said to Ka'b bin Murrah رضی اللہ عنہ, tell us a Hadith from the Messenger of Allah (ﷺ), but be careful. He said: I heard the Messenger of Allah (ﷺ) say: “Whoever frees a Muslim man, he will be his ransom from the Fire; each of his bones will suffice (as a ransom) for each of his bones. Whoever frees two Muslim women, they will be his ransom from the Fire; each of their two bones will suffice (as a ransom) for each of his bones.”

“I said: 'O Messenger of Allah (ﷺ), which slave is best?' He said: ‘The one who is most precious to his master and most valuable in price.' ”

The Prophet (ﷺ) said: “Whoever becomes the master of a Mahram relative (with whom marriage is not lawful), he becomes free.”

The Messenger of Allah (ﷺ) said: “Whoever becomes the master of a Mahram relative, he becomes free.”

“Umm Salamah freed me but stipulated that I should serve the Prophet (ﷺ) as long he lived.”

The Messenger of Allah (ﷺ) said: “Whoever frees his share of a slave or part of his share, must pay from his wealth if he has any wealth if he has any wealth (in order to buy the rest of the slave's freedom). If he does not have wealth, then the slave should be asked to work for the price (of his freedom), without that causing him too much hardship.”

The Messenger of Allah (ﷺ) said: “Whoever frees his share of a slave, the price of the slave should be fairly evaluated, and he (the partner who initiated this process) should free him (in full, by giving the rest of his price to the other co-owners), if he has enough wealth to do so. Otherwise, he will have freed whatever he freed.”

The Messenger of Allah (ﷺ) said: “Whoever frees a slave who has some wealth, the slave's wealth belongs to him, unless the master stipulates that it will belong to him.” (One of the narrators) Ibn Lahiah said (in his narration): "Unless the master make n exception for that.

`Abdullah رضی اللہ عنہ said to him: “O Umair, I have set you free in a good way. I heard the Messenger of Allah (ﷺ) say: 'Any man who frees a slave and does not say anything about his (the slave's) wealth, it belongs to him (the slave).' So tell me, how much wealth do you have?”

The Messenger of Allah (ﷺ) was asked about illegitimate children. He said: “Two sandals in which I wage Jihad are better than freeing an illegitimate child.”

She had a male slave and a female slave who were married. She said: “O Messenger of Allah (ﷺ), I want to free them both.” The Messenger of Allah (ﷺ) said: “If you free them, then start with the man before the woman.”
