Tell them: "O men, it's my duty to warn you clearly." 49 The righteously striving believers will receive forgiveness and honorable sustenance. 50 And those who strive against Our signs to void them -- they shall be the inhabitants 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 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 At the same time those who have been given knowledge may know that this is the truth from your Lord, and come to believe in it, and their hearts become submissive to Him. Verily God guides those who believe, to the even path. 54 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 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 they who disbelieved and denied Our signs - for those there will be a humiliating punishment. 57
