Coitus Interruptus With Enslaved Women
The narration is not allowing or disallowing anything. It should be kept in mind that as a societal norm, the nikah of captive women was considered absolved once they were captured. It should also be remembered that nikah entails a public announcement of intimate relationship between two people – a condition that was considered as a default in case of slave women at that time. Most narrations do not relate the context so it should not be assumed.
The context clearly is: The captive women with whom the companions desired sex and asked the Prophet’s advice. The Prophet by giving them advice allowed it. Maybe the hadith is problematic, Ghamidi sb can shed more light. Thanks
