SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 And [know that] those who attain to faith and do righteous deeds shall be granted forgiveness of sins and a most excellent sustenance; 50 But the ones who strove against Our verses, [seeking] to cause failure - those are the companions of Hellfire. 51 Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise: 52 (This He permits) in order that He makes satan's interjections a temptation for those in whose hearts is a sickness and those whose hearts are hardened and the harmdoers are in a wide schism, 53 And that those who have been given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path. 54 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 55 The sovereignty on that Day will be that of Allah (the one Who has no partners). He will judge between them. So those who believed (in the Oneness of Allah Islamic Monotheism) and did righteous good deeds will be in Gardens of delight (Paradise). 56 And for those who reject Faith and deny our Signs, there will be a humiliating Punishment. 57
