(49) باب الْمَبْتُوتَةِ لاَ يَرْجِعُ إِلَيْهَا زَوْجُهَا حَتَّى تَنْكِحَ زَوْجًا غَيْرَهُ
Narrated Aisha, Ummul Mu'minin:
The Messenger of Allah (ﷺ) was asked about a man who divorced his wife three times, and she married another who entered upon her, but divorced her before having intercourse with her, whether she was lawful for the former husband. She said: The Prophet (ﷺ) replied: She is not lawful for the first (husband) until she tastes the honey of the other husband and he tastes her honey.
