Shirk is of two kinds: greater and lesser. Greater shirk is everything which Allah has named shirk and which expels its doer from the religion — such as worshipping idols, calling upon the dead, slaughtering or vowing for other than Allah, or believing that anyone besides Allah independently controls benefit and harm. Lesser shirk is everything which the Lawgiver named shirk but which does not expel from the religion — such as ar-riya'' (showing off in worship), swearing by other than Allah, and saying ''what Allah and you willed.'' The Prophet (ﷺ) called ar-riya'' "the lesser shirk" because the doer intends in his worship someone other than Allah alongside Him. Lesser shirk is more dangerous to a believer than the major sins, because a believer hates the major sins yet may not even notice when ar-riya'' enters his heart.
