Bukhari

And (in Surah An-Nur) the statement of Allah, «والذين يبتغون الكتاب مما ملكت أيمانكم فكاتبوهم إن علمتم فيهم خيرا وآتوهم من مال الله الذي آتاكم‏» "And those of your slaves who seek a contract (of emancipation), contract with them if you know there is good in them. And give them from the wealth of Allah which He has given you." Ruh bin 'Ubadah narrated from Ibn Jurayj, who said: I asked 'Ata bin Abi Rabah, "If I know that my slave has wealth and he wants to make a contract (of emancipation), is it obligatory upon me to contract with him?" He said, "I think that (in such a case) the contract becomes obligatory." 'Amr bin Dinar narrated: I asked 'Ata, "Do you narrate this from anyone?" He replied, "No." (Then he remembered) and he informed me that Musa bin Anas informed him that Sirin (the father of Ibn Sirin) requested Anas (may Allah be pleased with him) to contract with him (for emancipation). (He was a slave of Anas, may Allah be pleased with him) and he was also wealthy. But Anas (may Allah be pleased with him) refused. So Sirin went to 'Umar (may Allah be pleased with him). 'Umar (may Allah be pleased with him) said (to Anas), "Make the contract with him." He still refused, so 'Umar (may Allah be pleased with him) struck him with a whip and recited this verse, «فكاتبوهم إن علمتم فيهم خيرا‏» "If you see good in them, then contract with them." So Anas (may Allah be pleased with him) made the contract.

Narrated 'Aishah (ra) that Barira came to seek her help writing of emancipation and she had to pay five Uqiya (of gold) by five yearly installments. 'Aishah said to her, "Do you think that if I pay the whole sum at once, your masters will sell you to me, and I will free you and your Wala' will be for me." Barira went to her masters and told them about that offer. They said that they would not agree to it unless her Wala' would be for them. 'Aishah further said, "I went to Allah's Messenger (saws) and told him about it." Allah Messenger (saws) said to her, "Buy Barira and manumit her and the Wala' will be for the liberator." Allah's Messenger (saws) then got up and said, "What about those people who stipulate conditions that are not present in Allah's Laws? If anybody stipulates a condition which is not in Allah's Laws, then what he stipulates is invalid. Allah's Condition (Laws) are the truth and are more solid."
