SAY [O Muhammad]: "O men! I am but a plain warner [sent by God] unto you!" 49 Those who believe and do good works, theirs shall be forgiveness and a generous provision; 50 And those who strive against Our signs to void them -- they shall be the inhabitants 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 He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers, etc.) are in an opposition far-off (from the truth against Allah's Messenger and the believers). 53 And so those who were given knowledge may know that it is the truth from your Lord and [therefore] believe in it, and their hearts humbly submit to it. And indeed is Allah the Guide of those who have believed to a straight path. 54 The infidels will remain in doubt about it till the Hour overtakes them unawares, or the punishment of the barren day destructive should come upon them. 55 The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, 56 And (as for) those who disbelieve in and reject Our communications, these it is who shall have a disgraceful chastisement. 57
