Abu Ja'far al-Nafaili عبد الله بن محمد أبو جعفر النفيلي الحران · Divorce (Kitab Al-Talaq)

A woman embraced Islam during the time of the Messenger of Allah (ﷺ); she then married. Her (former) husband then came to the Prophet (ﷺ) and said: Messenger of Allah, I have already embraced Islam, and she had the knowledge about my Islam. The Messenger of Allah (ﷺ) took her away from her latter husband and restored her to her former husband.
