Ibn 'Umar (RA) reported that 'A'isha decided to buy a slave-girl and then set her free, but her masters said: We are prepared to sell her to you on the condition that her right of inheritance would vest with us. She (Hadrat A'isha) made a mention of that to Allah's Messenger ( صلی اللہ علیہ وسلم ) whereupon he said: This should not stand in your way. The right of inheritance vests in one who emancipates.
