عَنْ أَبِي هُرَيْرَةَ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى أَنْ تُنْكَحَ الْمَرْأَةُ عَلَى عَمَّتِهَا أَوِ الْعَمَّةُ عَلَى بِنْتِ أَخِيهَا وَالْمَرْأَةُ عَلَى خَالَتِهَا أَوِ الْخَالَةُ عَلَى بِنْتِ أُخْتِهَا لَا تُنْكَحُ الصُّغْرَى عَلَى الْكُبْرَى وَلَا الْكُبْرَى عَلَى الصُّغْرَى. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ والدارمي وَالنَّسَائِيّ وَرِوَايَته إِلَى قَوْله: بنت أُخْتهَا

Ibn ‘Abbas told that a woman who had accepted Islam married, and her husband (i.e. the one she had left to marry another when she became a Muslim) went to the Prophet and said, "Messenger of God, I have accepted Islam and she knew that I had done so.” So God’s Messenger took her away from her second husband and restored her to her first. In a version he said, “She accepted Islam along with me,” so he restored her to him. Abu Dawud transmitted it.
