Idolatry means considering a person or another being, or a concept as equal to or higher than Allah in terms of estimating, attributing significance, preference, and holding superior, and to act with this distorted point of view. Allah describes this situation as “associating with Allah any other God”. In other words, to claim that somebody or something else has any of the attributes of Allah means ascribing a partner to Allah. Allah has proclaimed in the Quran that idolatry will not be forgiven: 
Allah does not forgive anything being associated with Him but He forgives whoever He wills for anything other than that. Anyone who serves gods other than Allah is guilty of a terrible crime. (Surat an-Nisa: 48)
