Tell them: "O men, it's my duty to warn you clearly." 49 So those who believed and did good deeds, for them are forgiveness, and an excellent sustenance. 50 And those who strive in Our signs with the intention of disputing, are the people of fire. 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 (This He permits) in order that He makes satan's interjections a temptation for those in whose hearts is a sickness and those whose hearts are hardened and the harmdoers are in a wide schism, 53 And that those who have been vouchsafed knowledge may know that it is the truth from thy Lord and may believe therein, and so their hearts may submit thereto. And verily Allah is the Guide of those who believe unto a path straight. 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
