Musannaf Ibn Abi Shaybah

Ismail (may Allah have mercy on him) says that I asked Sha'bi (may Allah have mercy on him) that regarding the mukatab who dies leaving behind wealth and children, what decision did Shurayh (may Allah have mercy on him) make? He replied: Whatever amount of the contract of emancipation remains, it will be paid to his master, and whatever wealth remains will go to his children. Sha'bi (may Allah have mercy on him) said: Shurayh (may Allah have mercy on him) gave this verdict according to the statement of Abdullah (may Allah be pleased with him).
