And We have indeed sent Noble Messengers towards the nations that were before you – We therefore seized them with hardship and adversity so that, in some way, they may humbly plead. 42 When Our Torment reached them, why then did they not believe with humility? But their hearts became hardened, and Shaitan (Satan) made fair-seeming to them that which they used to do. 43 So, when they forgot what they were reminded of; We opened unto them the gates of everything until; when they rejoiced in what they were given, We seized them suddenly, and behold, they were sore confounded. 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher of the worlds. 45 Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away. 46 Say: "Can you imagine what your condition will be if God's chastisement befalls you, either suddenly or in a [gradually] perceptible manner? [But then - ] will any but evildoing folk [ever] be destroyed? 47 And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve. 48 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 49 (Muhammad), tell them, "I do not claim to have all the treasures of God in my hands, nor to know the unseen, nor do I claim to be an angel. I follow only what is revealed to me (from God)." Say to them, "Are the blind and the seeing equal?" Why then do you not think? 50
