Say: O mankind! I am only a plain warner unto you. 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 but those who strive to void Our verses, thinking they have escaped, shall be the 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 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 53 And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight Path. 54 And those who disbelieve shall not cease to be in doubt concerning it until the hour overtakes them suddenly, or there comes on them the chastisement of a destructive day. 55 On that Day of Dominion will be that of Allah: He will judge between them: so those who believe and work righteous deeds will be in Gardens of Delight. 56 whereas for those who were bent on denying the truth and gave the lie to Our messages, there shall be shameful suffering in store. 57
