Say thou: mankind! I am unto you only a warner manifest. 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 Those who try to challenge Our miracles will be the dwellers of hell." 51 Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-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 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 Those who deny the truth will continue in doubt until the [Last] Hour suddenly comes upon them or the scourge of the woeful Day descends upon them. 55 The Sovereignty on that day will be Allah's, He will judge between them. Then those who believed and did good works will be in Gardens of Delight, 56 And those who disbelieved and belied Our signs - then these! for them will be a torment ignominous. 57
