Say, "O people, I am sent only to give you clear warning." 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 but those who strive to void Our verses, thinking they have escaped, shall be the people of Hell' 51 Never did We send a messenger or a prophet before thee, but, when he framed a desire, Satan threw some (vanity) into his desire: but Allah will cancel anything (vain) that Satan throws in, and Allah will confirm (and establish) His Signs: for Allah is full of Knowledge and Wisdom: 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 so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path. 54 And those who disbelieve will not cease to be in doubt thereof until the Hour cometh upon them on a sudden, or there cometh upon them the torment of a Barren Day. 55 The Kingdom upon that day shall belong to God, and He shall judge between them. As for those who believe, and do deeds of righteousness, they shall be in Gardens of Bliss. 56 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
