Say thou: mankind! I am unto you only a warner manifest. 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends of the Fire! 51 And We did not send before you any apostle or prophet, but when he desired, the Shaitan made a suggestion respecting his desire; but Allah annuls that which the Shaitan casts, then does Allah establish His communications, and Allah is Knowing, Wise, 52 [And He allows doubts to arise] so that He might cause whatever aspersion Satan may cast [against His prophets] to become a trial for all in whose hearts is disease and all whose hearts are hardened: for, verily, all who are [thus] sinning [against themselves] are most deeply in the wrong. 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 will not cease to be in doubt thereof until the Hour cometh upon them on a sudden, or there cometh upon them the torment of a Barren Day. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
