Say, "O people, I am only to you a clear warner." 49 Then those who believe and work righteous works - for them is forgiveness and a provision honourable. 50 whereas those who strive against Our Signs, seeking to profane them, they are the friends of the Fire! 51 Never sent We a messenger or a prophet before thee but when He recited (the message) Satan proposed (opposition) in respect of that which he recited thereof. But Allah abolisheth that which Satan proposeth. Then Allah establisheth His revelations. Allah is Knower, 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 And that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way. 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 On that Day, all dominion shall [visibly] belong to God, He shall judge [all men and make a distinction] between them: thus, all who had attained to faith and did righteous deeds shall find themselves in gardens of bliss, 56 While those who disbelieved and denied Our revelations, for them will be a shameful doom. 57
