Judaism, Christianity and Islam forbade adultery
In the Old Testament, we read: “You shall not commit adultery”
Also: "If a man commits adultery with another man’s wife—with the wife of his neighbor—both the adulterer and the adulteress are to be put to death."
Jesus said: ‘You shall not commit adultery,’
God said in the Quran: “And do not approach unlawful sexual intercourse. Indeed, it is ever an immorality and is evil as a way.”
The Quran says:
The adulteress and the adulterer, flog each of them a hundred stripes (that affects the skin only) and let not pity for them detain you concerning (the application of) Lord’s Religion, if you believe in God and the Last Day, and let a party of the believers witness their torment.
