Proclaim, “O mankind, I am for you only a clear Herald of Warning.” 49 Those who believe, and do deeds of righteousness -- theirs shall be forgiveness and generous provision. 50 But those who strive against Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), to frustrate and obstruct them, they will be dwellers of the Hell-fire. 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 (This He permits) in order that He makes satan's interjections a temptation for those in whose hearts is a sickness and those whose hearts are hardened and the harmdoers are in a wide schism, 53 And that those who have been vouchsafed knowledge may know that it is the truth from thy Lord and may believe therein, and so their hearts may submit thereto. And verily Allah is the Guide of those who believe unto a path straight. 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 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 those who disbelieved and denied Our signs – for them will be a disgraceful punishment. 57
