Hazrat Sha'bi (may Allah have mercy on him) says that in the case of the death of the master of an Umm Walad slave woman, her waiting period ('iddah) is one menstrual cycle. If you consider her waiting period to be three menstrual cycles, then why do you not make her an heir of the master?!

Hazrat Ata (may Allah have mercy on him) and Hazrat Tawus (may Allah have mercy on him) state that when an Umm Walad slave woman or a slave woman who had marital relations with her master passes away, her waiting period (‘iddah) is two months and five nights.

Hazrat Yahya bin Saeed (may Allah have mercy on him) says that someone mentioned before Hazrat Qasim (may Allah have mercy on him) that Abdul Malik bin Marwan (may Allah have mercy on him) separated men from such wives who were umm walad (slave women who bore children to their masters) of their masters. But after one or two menstrual cycles, their marriages were conducted. Abdul Malik bin Marwan (may Allah have mercy on him) ordered that they should observe an 'iddah of four months and ten days. Upon hearing this, Hazrat Qasim (may Allah have mercy on him) said, "Subhan Allah! Allah Almighty says in the Holy Qur'an { وَالَّذِینَ یُتَوَفَّوْنَ مِنْکُمْ وَیَذَرُونَ أَزْوَاجًا } so are these masters their husbands?"

Hazrat Yahya bin Abi Kathir (may Allah have mercy on him) narrates that Hazrat Amr bin Al-Aas (may Allah be pleased with him) ordered the Umm Walad who had been set free to observe the waiting period of three menstrual cycles, and he wrote this decision to Hazrat Umar (may Allah be pleased with him). Hazrat Umar (may Allah be pleased with him) approved of his opinion.

Hazrat Hasan (may Allah be pleased with him) used to say that when an Umm Walad is set free, her waiting period (‘iddah) is three menstrual cycles.

Ibrahim (may Allah have mercy on him) said that if a man frees his umm walad or dies leaving her, her waiting period (‘iddah) is three menstrual cycles.

Hazrat Mak’hool (may Allah have mercy on him) says that if a man frees his umm walad, her waiting period (‘iddah) is two menstrual cycles. Hazrat Zuhri (may Allah have mercy on him) says that her waiting period is three menstrual cycles.

19841 - Al-Zuhri said: (Three) (1) periods.

Hazrat Jabir bin Zaid (may Allah be pleased with him) says that when a man frees such a slave woman with whom he had marital relations, then if she experiences menstruation, she will observe a waiting period of three menstrual cycles, and if she does not menstruate, she will observe a waiting period of one month.

Hazrat Ibn Umar (may Allah be pleased with both of them) narrates that the waiting period (‘iddah) of an umm walad is one menstrual cycle, whether she is set free or her master passes away.
