Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 For those who believe and do the right is forgiveness and gracious provision. 50 Those who try to challenge Our miracles will be the dwellers of hell." 51 Never have We sent a Messenger or a Prophet before you, but when he hoped, satan tampered with his hope. But Allah supersedes the tampering of satan and confirms His verses. And Allah is the Knower, the 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 so that those who are given knowledge may realize that this is the truth from your Lord and thus believe in it, and so that in their hearts they may humbly submit to Him. God will surely guide the faithful to a straight 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 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
