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 profane them, they are the friends of the Fire! 51 And all the Noble Messengers or Prophets whom We sent before you – it occurred with all of them – that whenever they recited (the message) Satan included a bit (from his own speech) in their recitation to the people; so Allah obliterates what Satan includes and then Allah fortifies His verses; and Allah is All 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 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 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
