Musannaf Ibn Abi Shaybah

Hazrat Ibn Ma'qil narrates that Hazrat Aisha (may Allah be pleased with her) had to free a slave from the descendants of Ismail. Some captives came from Yemen; Mus'ar, the narrator, says that he thinks they were from the tribe of Khawlan. She was forbidden to free any of them. Then some captives came from Mudar; the narrator says that he thinks they were from Banu Anbar. Then she was ordered to free one from among them.

Hazrat Amir was asked about a person who made a vow that if he entered so-and-so's house, he would free two slaves from among the descendants of Ismail, and then he entered that person's house. He replied: There is no expiation upon him. The person said: I do not find these two (slaves). He replied: Then fast continuously for four months, two months of fasting for each slave; perhaps this may serve as some expiation.
