SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 So those who believe (in the Oneness of Allah Islamic Monotheism) and do righteous good deeds, for them is forgiveness and Rizqun Karim (generous provision, i.e. Paradise). 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 He makes Satan's suggestions a trial for those whose hearts are diseased or hardened, and, surely, the wrongdoers are far gone in error, 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 And the disbelievers will always be in doubt of it, to the extent that the Last Day will suddenly come upon them, or will come upon them the punishment of a day the result of which is not at all good for 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 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
