Tell them: "O men, it's my duty to warn you clearly." 49 Those who believe and do good works, for them is pardon and a rich provision; 50 But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-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 This is in order to make the interpolations of Satan a test for those whose hearts are diseased and hardened: Surely the sinners have gone far in dissent. 53 And that those who have been given knowledge may know that it is the truth from thy Lord, so that they may believe therein and their hearts may submit humbly unto Him. Lo! Allah verily is guiding those who believe unto a right path. 54 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes them. 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 the unbelievers who called Our revelations lies will suffer humiliating torment. 57
