Then God would remove Satan's temptations and strengthen His revelations. God is All-knowing and All-wise. 52 That he may make that which the Satan casteth forth a temptation for those in whose heart is a disease and whose hearts are hardened - and the wrong-doers are in divergence far-off 53 At the same time those who have been given knowledge may know that this is the truth from your Lord, and come to believe in it, and their hearts become submissive to Him. Verily God guides those who believe, to the even path. 54 And those who disbelieve shall not cease to be in doubt concerning it until the hour overtakes them suddenly, or there comes on them the chastisement of a destructive day. 55 The dominion on that Day will be Allah's; He shall judge between them; then those who believed and worked righteous works shall be in the Gardens of Delight. 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
