Say, "O people, I am sent only to give you clear warning." 49 For those who believe and do the right is forgiveness and gracious 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 [And He allows doubts to arise] so that He might cause whatever aspersion Satan may cast [against His prophets] to become a trial for all in whose hearts is disease and all whose hearts are hardened: for, verily, all who are [thus] sinning [against themselves] are most deeply in the wrong. 53 and that they who have been given knowledge may know that it is the truth from thy Lord and believe in it, and so their hearts be humble unto Him; and assuredly God ever guides those who believe to a straight path. 54 Those who deny the truth will continue in doubt until the [Last] Hour suddenly comes upon them or the scourge of the woeful Day descends upon them. 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 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
