Say: O people! I am only a plain warner to you. 49 Those who believe and do good deeds shall be forgiven and shall receive an honourable provision. 50 "But those who strive against Our Signs, to frustrate them,- they will be Companions 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 So that He may make what the devil includes a trial for those in whose hearts is a disease, and those whose hearts are hardened; indeed the unjust are extremely quarrelsome. 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 The order will be God's on that Day; He will judge between them. Then those who had come to believe and done the right will be in gardens of delight. 56 but those who deny the truth and deny Our signs will receive a humiliating punishment. 57
