Say (O Muhammad SAW): "O mankind! I am (sent) to you only as a plain warner." 49 "Those who believe and work righteousness, for them is forgiveness and a sustenance most generous. 50 But those who try to defeat Our signs are people of Hell. 51 Yet whenever We sent forth any apostle or prophet before thee, and he was hoping [that his warnings would be heeded,] Satan would cast an aspersion on his innermost aims: but God renders null and void whatever aspersion Satan may cast; and God makes His messages clear in and by themselves for God is all-knowing, wise. 52 that He may make what Satan casts a trial for those in whose hearts is sickness, and those whose hearts are hard; and surely the evildoers are in wide schism; 53 And so that the people given the knowledge may know that it is the truth from your Lord, in order that they may accept faith in it, therefore their hearts may humble before Him; and indeed Allah will guide the believers on the Straight Path. 54 And the unbelievers will not cease to be in doubt of it, until the Hour comes on them suddenly, or there shall come upon them the chastisement 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 And those who disbelieved and belied Our Verses (of this Quran), for them will be a humiliating torment (in Hell). 57
