SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 The righteously striving believers will receive forgiveness and honorable sustenance. 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 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 those who disbelieve will not cease to be in doubt about it (this Quran) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection). 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 for those who disbelieved Our verses and belied there awaits a humbling punishment. 57
