Surah 17. Al-Israa, Ayah 32

Lit., "do not come near adultery", thus intensifying the prohibition. It is to be noted that the term zina signifies all sexual intercourse between a man and a woman who are not husband and wife, irrespective of whether either of them is married to another partner or not; hence, it denotes both "adultery" and "fornication" in the English senses of these terms.

Adultery is not only shameful in itself and inconsistent with any self-respect or respect for others, but it opens the road to many evils. It destroys the basis of the family: it works against the interests of children born or to be born; it may cause murders and feuds and loss of reputation and property, and also loosen permanently the bonds of society. Not only should it be avoided as a sin, but any approach or temptation to it should be avoided.
