Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 The righteously striving believers will receive forgiveness and honorable sustenance. 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 So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition, 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 whereas those who are bent on denying the truth will not cease to be in doubt about Him until the Last Hour comes suddenly upon them and [supreme] suffering befalls them on a Day void of all hope. 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 A humiliating chastisement awaits those who disbelieved and denied Our Signs. 57
