He replied, "No, it is unlawful."

[Agreed upon] .

I replied, "No." He again said, "Sell it to me." So I sold it to him for one Uqiya. However I stipulated that I should be allowed to ride it home. Then when I reached (home), I took the camel to him and he paid me its price in cash. I then went back and he sent someone after me. (When I came), he said, "Do you think that I asked you to reduce the value of your camel's price to take it? Take your camel and your money, for it is yours." [Agreed upon; and this is Muslim's wording] .

Narrated Maimuna (RA), the wife of the Prophet ( صلی اللہ علیہ وسلم ): A mouse fell into some ghee and died.

Ahmad and an-Nasa'i added: "into a solid ghee."

Narrated 'Aishah (RA): Barirah came to her and said, "I had arranged to buy my freedom for nine Uqiya; one Uqiyah to be paid annually, so help me." 'Aishah (RA) replied, "If your people are pleased that I should pay (the amount) to them, and I shall have the right to inherit from you, I shall do so." Barira went to her people and told them about it, but they refused the offer. When she came back Allah's Messenger ( صلی اللہ علیہ وسلم ) was sitting (in the house). She said, "I offered that to them, but they insisted that the right to inherit from me should be theirs." The Prophet ( صلی اللہ علیہ وسلم ) heard that and 'Aishah (RA) told him about it. So, he said to 'Aishah (RA), "Take her and stipulate that the right to inherit from her will be yours, for the right of inheritance from her will be yours, for the right of inheritance belongs only to the one who has set a slave free." 'Aishah (RA) did so. Allah's Messenger ( صلی اللہ علیہ وسلم ) then stood up among the people to address them. So, after praising and extolling Allah, he said, "To proceed; what is the matter with some men who make conditions which are not in the Book of Allah, the Might, the Majestic? Any condition which is not in Allah's Book is invalid. Even if there are a hundred conditions, Allah's Decision is more valid and Allah's Condition is more binding. The right of inheritance belongs only to the one who has set a slave free." [Agreed upon and the wording is al-Bukhari's] . Muslim has: "Buy her, set her free and make the stipulation that the right to inherit from her will be yours."
