Her (Barira's) husband was a slave, so Allah's Messenger (ﷺ) gave her the option (either to retain her matrimonial relation with her husband or sever it off). She opted to break off (and secure freedom for her even from the matrimonial alliance). And if he were free he would not have given her the option. In the hadith narrated on the authority (of this chain of transmitters) these words are not found: Amma ba'du.
Sahih Muslim Book 20, Hadith 11
← Previous Hadith
Barira came to me and said: My family (owners) have made contract with me (for granting freedom) for nine 'uqiyas (of silver) payable in nine years, one 'uqiya every year. Help me (in making this payment). I said to her: If your family so desires, I am prepared to make them the full payment in one instalment, and thus secure freedom for you, but the right of inheritance will vest in me, if I do so. She (Barira) made a mention of that to her family, but they refused (except) on the condition that the right of inheritance would vest in them. She came to me and made mention of if She ('A'isha) said: I scolded her. She (Barira) said: By Allah, it is not possible (they will never agree to it). And as she was saying it, Allah's messenger (ﷺ) heard, and he asked me, I informed him and he said: Buy her and emancipate her, and let the right of inherit- ance vest in them, for they cannot claim it (rightfully) since the right of inherritance vests with one who emancipates (the slave; therefore, these people have no right to lay such false claims). And I did so. She ('A'isha) said: Then Allah's Messenger (ﷺ) delivered a sermon in the evening. He extolled Allah and praised Him with what He deserves, and then said afterwards,: What has happened to the people that they lay down conditions which are not found in the Book of Allah? And the condition which is not found in the Book of Allah is invalid, even if its number is one hundred. The Book of Allah is more true (than any other deed) and the condition laid down by Allah is more binding (than any other condition). What has happened to the people among you that someone among you says:" Emancipate so and so, but the right of inheritance vests in me"? Verily, the right of inheritance vests in one who emancipates.
Sahih Muslim Book 20, Hadith 10 Next Hadith → 'A'isha (Allah be pleased with her) said: There were three issues which were clarified in case of Barira: her owners had decided to sell her on the condition that the right of her inheritance would vest with them. She ('A'isha) said: I made a mention of that to Allah's Apostle (ﷺ) and he said: Buy her and emancipate her, for verily the right of inheritance vests with one who emancipates. She said that she emancipated (her) and Allah's Messenger (ﷺ) gave her the option (either to retain her matrimonial alliance or break it after emancipation). She (taking advantage of the option) opted for herself (the severing of matrimonial alliance). 'A'isha said: The people used to give her charity and she gave us that as gift. I made a mention of it to Allah's Apostle (ﷺ), whereupon he said: That is charity for her but gift for you, so take that.
