Tell them: "O men, it's my duty to warn you clearly." 49 The righteously striving believers will receive forgiveness and honorable sustenance. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends of the Fire! 51 Yet whenever We sent forth any apostle or prophet before thee, and he was hoping [that his warnings would be heeded,] Satan would cast an aspersion on his innermost aims: but God renders null and void whatever aspersion Satan may cast; and God makes His messages clear in and by themselves for God is all-knowing, wise. 52 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 53 And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight 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 On that Day all sovereignty shall be Allah's and He will judge among them. Then those who believed and acted righteously shall be in Gardens of Bliss. 56 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
