SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto 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 So that He may make what the devil includes a trial for those in whose hearts is a disease, and those whose hearts are hardened; indeed the unjust are extremely quarrelsome. 53 so that those who have received knowledge would know and believe that whatever happens with the Prophets and Messengers is the Truth from their Lord and will believe it. This will cause their hearts to become filled with awe. God guides the believers to the right path. 54 And those who disbelieve will not cease to be in doubt thereof until the Hour cometh upon them on a sudden, or there cometh upon them the torment of a Barren Day. 55 The order will be God's on that Day; He will judge between them. Then those who had come to believe and done the right will be in 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
