Sexuality in Islam, particularly Islamic jurisprudence of sex (Arabic: الفقه الجنسي) and Islamic jurisprudence of marriage (Arabic: فقه النكاح) are the codifications of Islamic scholarly perspectives and rulings on sexuality, which both in turn also contain components of Islamic family jurisprudence, Islamic marital jurisprudence, hygienical, criminal and bioethical jurisprudence, which contains a wide range of views and laws, which are largely predicated on the Quran, and the sayings attributed to Muhammad (hadith) and the rulings of religious leaders (fatwa) confining sexual intercourse to relationships between men and women. All instructions regarding sex in Islam are considered parts of, firstly, Taqwa or obedience and secondly, Iman or faithfulness to God. Sensitivity to gender difference and modesty outside of marriage can be seen in current prominent aspects of Muslim cultures, such as interpretations of Islamic dress and degrees of gender segregation.
