Islamic views on concubinage

Concubinage is an arrangement in which someone has a romantic or sexual relationship with someone other than their spouse, but it is not considered a marriage. Islamic views on concubinage are not entirely clear, but generally it is not seen as something accepted by Islam. This is because in Islam, marriage is seen as a sacred bond between two people, and if there is a relationship with someone other than a spouse, it is considered to be a serious violation of the faith. Additionally, Islamic law forbids sexual relationships outside of marriage, so having a relationship like this would be against the teachings of Islam.
