The word(s) "adultery" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) And come not near unto adultery. Lo! it is an abomination and an evil way.

(2) And those who cry not unto any other god along with Allah, nor take the life which Allah hath forbidden save in (course of) justice, nor commit adultery - and whoso doeth this shall pay the penalty;

(3) O Prophet! If believing women come unto thee, taking oath of allegiance unto thee that they will ascribe no thing as partner unto Allah, and will neither steal nor commit adultery nor kill their children, nor produce any lie that they have devised between their hands and feet, nor disobey thee in what is right, then accept their allegiance and ask Allah to forgive them. Lo! Allah is Forgiving, Merciful.
