If the master is dead when the emancipated slave dies
A person died and left no heirs or consanguinity of any kind. He was a slave and then was freed and those who set him free are still alive. To whom should his property go?
If the reality is as you have mentioned, his property should go to those who set him free whether male or female. If those who set him free are not alive at the death of the freed slave, his property should go to the children of those who set him free. (Part No. 16; Page No. 567) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
