Chapter 21: The Book of Emancipating Slaves
' A' isha (Allah be pleased with her) reported: She wanted to buy Barira with a view to emancipating her. They (the sellers) laid down the condition that the right of inheritance would vest (with them). She (Hadrat 'A' isha) made a mention of that to Allah' s Messenger (ﷺ), whereupon he said: Buy her and emancipate her for the right of inheritance vests with one who emancipates. Allah' s Messenger (ﷺ) was given meat as gift. They (his Companions) said to Allah' s Apostle (ﷺ): This was given as charity to Barira, whereupon he said: That is charity for her but gift for us. And she was given option (to retain her matrimonial alliance or to break it). Abd al-Rahman said: Her husband was a free man. Shu' ba said: I then asked him (one of the narrators) about Barira' s husband (whether he had been a free mart or a slave), whereupon he said: I do not know.
