Say (Prophet Muhammad): 'O people, I have been sent to warn you plainly. 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 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 that He may make what Satan casts a trial for those in whose hearts is sickness, and those whose hearts are hard; and surely the evildoers are in wide schism; 53 And that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way. 54 whereas those who are bent on denying the truth will not cease to be in doubt about Him until the Last Hour comes suddenly upon them and [supreme] suffering befalls them on a Day void of all hope. 55 On that Day all control will belong to God. He will judge between them. Those who believe and do good deeds shall enter the Gardens of Bliss, 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
