Hassan ibn Ali bin Abi Talib · 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.

The Prophet (ﷺ) said: There is no prostitution in Islam. If anyone practised prostitution in pre-Islamic times, the child will be attributed to the master (of the slave-woman). He who claims his child without a valid marriage or ownership will neither inherit nor be inherited.
