Say thou: mankind! I am unto you only a warner manifest. 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 And those who strive against Our signs to void them -- they shall be the inhabitants of Hell. 51 And We did not send before you any apostle or prophet, but when he desired, the Shaitan made a suggestion respecting his desire; but Allah annuls that which the Shaitan casts, then does Allah establish His communications, and Allah is Knowing, 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 the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 And the unbelievers will not cease to be in doubt of it, until the Hour comes on them suddenly, or there shall come upon them the chastisement of a barren day. 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 While those who disbelieved and denied Our revelations, for them will be a shameful doom. 57
