This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.
Sahih Muslim Book 20, Hadith 15
← Previous Hadith 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.

Sahih Muslim Book 20, Hadith 14 Next Hadith → 'A'isha reported that the husband of Barira was a slave.
