Those who Invoke Not, with Allah and Commits Haraam (sin‘s)

Those who invoke not, with Allah, any other god, nor slay such life as Allah has made sacred except for just cause, nor commit fornication; and any that does this (not only) meets punishment.

(But) the Penalty on the Day of Judgment will be doubled to him, and he will dwell therein in ignominy (disgrace and dishonor),

Unless he repents, believes, and works righteous deeds, for Allah will change the evil of such persons into good, and Allah is Oft-Forgiving, Most Merciful.

(Al-Furqan 25:68-70)
