Say: 'O men, I am only for you a plain warner.' 49 So those who believe and act righteously shall be granted forgiveness and an honourable sustenance, 50 But those who try to defeat Our signs are people of Hell. 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 He makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 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 And the unbelievers will not cease to be in doubt of it, until the Hour comes on them suddenly, or there shall come upon them the chastisement of a barren day. 55 For Allah only is the kingship on that day; He will judge between them; so those who believed and did good deeds are in Gardens of content. 56 And they who disbelieved and denied Our signs - for those there will be a humiliating punishment. 57
