(And (be mindful of) the Day) which is the Day of Judgement (when He will say) to idol worshippers: (Call those partners of Mine) i.e. your deities (whom ye pretended) whom you worshipped and claimed they were My partners so that they defend you against my chastisement. (Then they will cry unto them, but they will not hear their prayer) they did not respond to them, (and We shall set a gulf of doom between them) We shall set a valley of fire between the worshippers and those who were worshipped; it is also said that this means: We set destruction between them in the Hereafter instead of the love and affection which was between them in the life of this world.
