When it was the time of his death a certain person of our people went and bought his mother. He set the condition that he buys her and sets her free; if after the death of her son so and so, son of so and so, when she will inherit his legacy, she must pay him one-half of what she will inherit. She must promise before Allah and the Messenger of Allah to fulfil this agreement. She agreed and promised before Allah and the Messenger of Allah to act according to the agreement. The man bought and freed her according to the condition and her son died thereafter. She inherited him because there was no other heir except her. Abu Ja‘far (a.s.), has said, ‘He has done a favor to her and has his rewards for it. He is a scholar of fiqh (Islamic laws) and Muslims stand by their conditions. She must complete the agreement about which she has promised before Allah and His messenger.”’
