Divorce (Kitab Al-Talaq)
Dawud :: Book 12 : Hadith 2231
Narrated Abdullah ibn Abbas:
A woman embraced Islam during the time of the Apostle of Allah (peace_be_upon_him); she then married. Her (former) husband then came to the Prophet (peace_be_upon_him) and said: Apostle of Allah, I have already embraced Islam, and she had the knowledge about my Islam. The Apostle of Allah (peace_be_upon_him) took her away from her latter husband and restored her to her former husband.
