And those who, having done something to be ashamed of, or wronged their own souls, earnestly bring Allah to mind, and ask for forgiveness for their sins,- and who can forgive sins except Allah?- and are never obstinate in persisting knowingly in (the wrong) they have done.
If under the influence of emotions, a person commits a minor or a major sin, the remembrance of Allah should forthwith alert and prompt him to seek His forgiveness as a seeker of real success and prosperity. There is none other Allah who can forgive sins. So those who put all their hopes in the intercession of others with Allah, will be disappointed when they face chastisement for their misdeeds.
