Say, "O people, I am sent only to give you clear warning." 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends of the 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 [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 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon 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 And (as for) those who disbelieve in and reject Our communications, these it is who shall have a disgraceful chastisement. 57
