Say thou: mankind! I am unto you only a warner manifest. 49 For those who believe and do the right is forgiveness and gracious provision. 50 "But those who strive against Our Signs, to frustrate them,- they will be Companions of the Fire." 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 (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 so that those to whom knowledge has been given will know that this is the truth from your Lord and so believe in it and that their hearts will be humble to Him. Indeed, Allah will surely guide those who believe to a Straight Path. 54 The unbelievers will never cease to doubt it until the Hour overtakes them suddenly or the punishment of the Barren Day comes upon them. 55 For Allah only is the kingship on that day; He will judge between them; so those who believed and did good deeds are in Gardens of content. 56 And those who disbelieved and belied Our Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
