Al-Haytham or Abu al-Haytham (may Allah have mercy on him) (the narrator Abu Bakr was in doubt about this) narrates that the Prophet (peace and blessings be upon him) gave Sawdah (may Allah be pleased with her) one divorce. So she sat in his (peace and blessings be upon him) path, and when he (peace and blessings be upon him) passed by, she asked him to take her back, and offered to give her turn to whichever of his wives he wished, hoping to be raised on the Day of Resurrection as his (peace and blessings be upon him) wife. So he (peace and blessings be upon him) took her back and accepted that.
