Say: O mankind! I am only a plain warner unto you. 49 And those who have believed and done righteous deeds - for them is forgiveness and noble provision. 50 Whereas those who strive against Our signs, seeking to defeat their purpose, shall be the inmates of the Fire. 51 And We have sent before thee no apostle or prophet but when he read the Satan cast forth suggestions in respect of his reading; then Allah abolisheth that which the Satan casteth forth; then Allah confirmeth His revelations; and Allah is 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 [God renders Satan's aspersions null and void] so that they who are endowed with [innate] knowledge might know that this [divine writ] is the truth from thy Sustainer, and that they aught believe in it, and that their hearts might humbly submit unto Him. For, behold, God does guide onto a straight way those who have attained to faith 54 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 55 On that Day of Dominion will be that of Allah: He will judge between them: so those who believe and work righteous deeds will be in Gardens of Delight. 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
