Say (O Muhammad): "O people! I have been sent to you only as a plain warner (before the Doom strikes you)." 49 For those who believe and do the right is forgiveness and gracious provision. 50 but those who strive to void Our verses, thinking they have escaped, shall be the people of Hell' 51 We sent not ever any Messenger or Prophet before thee, but that Satan cast into his fancy, when he was fancying; but God annuls what Satan casts, then God confirms His signs -- surely God is All-knowing, 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 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 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 The kingdom on that day shall be Allah's; He will judge between them; so those who believe and do good will be in gardens of bliss. 56 And those who disbelieved and belied Our Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
