Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 If only, when Our disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto them! 43 Then when they forgot that whereof they were reminded We opened upon them the doors of everything, until when they boasted of that which they were given, We laid hold of them on a sudden, and lo! they were dumbfounded. 44 Thus were the wicked people rooted out of existence to the last. All praise be to God, the Lord of all the worlds. 45 Say (to the disbelievers): "Tell me, if Allah took away your hearing and your sight, and sealed up your hearts, who is there - an ilah (a god) other than Allah who could restore them to you?" See how variously We explain the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), yet they turn aside. 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 We send the messengers only to give good news and to warn: so those who believe and mend (their lives),- upon them shall be no fear, nor shall they grieve. 48 Chastisement will befall those who reject Our signs because of their disobedience. 49 Say: 'I do not say to you, "I possess the treasuries of God"; I know not the Unseen. And I say not to you, "I am an angel"; I only follow what is revealed to me. Say: 'Are the blind and the seeing man equal? Will you not reflect?' 50
