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 in Our signs with the intention of disputing, are the people of fire. 51 And We have sent before thee no apostle or prophet but when he read the Satan cast forth suggestions in respect of his reading; then Allah abolisheth that which the Satan casteth forth; then Allah confirmeth His revelations; 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 given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path. 54 The unbelievers will not cease to be in doubt about it until the Hour suddenly comes upon them, or the chastisement of an ominous day overtakes them. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 But as for the unbelievers, who cried lies to Our signs; for them awaits a humbling chastisement. 57
