(30) باب فِي ادِّعَاءِ وَلَدِ الزِّنَا
Narrated Abdullah ibn Abbas:
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.
