Tell them: "O men, it's my duty to warn you clearly." 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 But the ones who strove against Our verses, [seeking] to cause failure - those are the companions of Hellfire. 51 We sent not ever any Messenger or Prophet before thee, but that Satan cast into his fancy, when he was fancying; but God annuls what Satan casts, then God confirms His signs -- surely God is All-knowing, All-wise -- 52 That He may make that which the devil proposeth a temptation for those in whose hearts is a disease, and those whose hearts are hardened - Lo! the evil-doers are in open schism - 53 and so that those to whom knowledge has been given will know that this is the truth from your Lord and so believe in it and that their hearts will be humble to Him. Indeed, Allah will surely guide those who believe to a Straight Path. 54 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes them. 55 The dominion on that Day will be Allah's; He shall judge between them; then those who believed and worked righteous works shall be in the Gardens of Delight. 56 but for those who disbelieved Our verses and belied there awaits a humbling punishment. 57
