Say: 'O men, I am only for you a plain warner.' 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 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 Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise: 52 that He may make what Satan casts a trial for those in whose hearts is sickness, and those whose hearts are hard; and surely the evildoers are in wide schism; 53 And so that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 The unbelievers will continue to doubt the Quran until the Hour of Doom suddenly sizes them or the torment of the last day strikes them. 55 On that Day all control will belong to God. He will judge between them. Those who believe and do good deeds shall enter the Gardens of Bliss, 56 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
