Abu Hurairah (RA) reported: 'A'isha (Allah be pleased with her) thought of buying a slave-girl and emancipating her, but her owners refused to (sell her but on the condition) that the right of inheritance would vest in them. She made a mention of that to Allah's Messenger ( صلی اللہ علیہ وسلم ) . whereupon he said: Let this (condition) not stand in your way for the right of inheritance vests with one who emancipates.
