Zina

Zināʾ (زِنَاء) or zina (زِنًى or زِنًا) is an Islamic law concerning unlawful sexual relations between Muslims who are not married to one another through a Nikah. It includes extramarital sex and premarital sex, such as adultery (consensual sexual relations outside marriage), fornication (consensual sexual intercourse between two unmarried persons), and homosexuality (consensual sexual relations between same-sex partners). Traditionally, a married or unmarried Muslim male could have sex outside marriage with a non-Muslim slave, with or without her consent, and such sex was not considered zina.
