Say: "O men! I am (sent) to you only to give a Clear Warning: 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 And those who strive against Our signs to void them -- they shall be the inhabitants 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 he may make that which the Satan casteth forth a temptation for those in whose heart is a disease and whose hearts are hardened - and the wrong-doers are in divergence far-off 53 And that those on whom knowledge has been bestowed may learn that the (Qur'an) is the Truth from thy Lord, and that they may believe therein, and their hearts may be made humbly (open) to it: for verily Allah is the Guide of those who believe, to the Straight Way. 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 The dominion on that Day will be Allah's; He shall judge between them; then those who believed and worked righteous works shall be in the Gardens of Delight. 56 And those who disbelieved and belied Our Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
