And indeed, We sent Our messages unto people before thy time, [O Prophet,] and visited them with misfortune and hardship so that they might humble themselves: 42 if only, when Our might came upon them, they had been humble! But their hearts were hard, and Satan decked out fair to them what they were doing. 43 And when they had forgotten that with which they have been admonished, We opened the gates of everything to them, until just as they were rejoicing in what they were given, We suddenly seized them and they were in utter despair. 44 and [in the end,] the last remnant of those folk who had been bent on evildoing was wiped out. For all praise is due to God, the Sustainer of all the worlds. 45 Say: "Imagine if God takes away your hearing and sight, and sets a seal on your hearts, what deity other than God will restore them to you?" See how We inflect Our signs: Even then 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 And We send not apostles but as announcers of good news and givers of warning, then whoever believes and acts aright, they shall have no fear, nor shall they grieve. 48 But those who deny Our messages will be seized by nemesis for being disobedient. 49 Say: 'I do not tell you that I have the treasuries of Allah or know the unseen, nor do I claim to be an angel. I follow only that which is revealed to me' Say: 'Are the blind and the seeing alike? Will you not think' 50
