Say (O Muhammad): "O people! I have been sent to you only as a plain warner (before the Doom strikes you)." 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 But those who try to defeat Our signs are people 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 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 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 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 sovereignty on that Day will be that of Allah (the one Who has no partners). He will judge between them. So those who believed (in the Oneness of Allah Islamic Monotheism) and did righteous good deeds will be in Gardens of delight (Paradise). 56 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
