In Islam, prohibitions against extramarital sex are strong and permissible marital sexual activities are familiar subjects.
This sensitivity to gender difference, gender seclusion and modesty outside of marriage can be seen in current prominent aspects of Islam, such as interpretations of Islamic dress and degrees of gender segregation. While most traditions discourage celibacy, all encourage strict chastity, modesty and privacy with regard to any relationships between genders, holding forth that their intimacy as perceived within Islam is largely reserved for marriage. Views and laws about sexuality in Islam are largely predicated on the Quran, the sayings of Muhammad ( hadith) and the rulings of religious leaders ( fatwa) confining sexual activity to marital relationships between men and women.
