Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 Those who believe and do good deeds shall be forgiven and shall receive an honourable provision. 50 While those who strive to thwart Our revelations, such are rightful owners of the Fire. 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 they who have been given knowledge may know that it is the truth from thy Lord and believe in it, and so their hearts be humble unto Him; and assuredly God ever guides those who believe to a straight path. 54 But those who disbelieve will not cease to be in doubt of it until the Hour comes upon them unexpectedly or there comes to them the punishment of a barren Day. 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 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
