Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 "But those who strive against Our Signs, to frustrate them,- they will be Companions of the 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 [That is] so He may make what Satan throws in a trial for those within whose hearts is disease and those hard of heart. And indeed, the wrongdoers are in extreme dissension. 53 And that those who have been given knowledge may know that it (this Quran) is the truth from your Lord, and that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the Straight 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 [All] sovereignty that Day is for Allah; He will judge between them. So they who believed and did righteous deeds will be in the Gardens of Pleasure. 56 and the unbelievers who called Our revelations lies will suffer humiliating torment. 57
