Verily, We sent (Messengers) to many nations before you (O Muhammad SAW). And We seized them with extreme poverty (or loss in wealth) and loss in health with calamities so that they might believe with 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 So, when they forgot (the warning) with which they had been reminded, We opened to them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them to punishment, and lo! They were plunged into destruction with deep regrets and sorrows. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 (Muhammad), ask them, "Have you ever considered that if God was to disable your hearing and vision and veil your hearts, could anyone besides Him restore them?" Look at how plainly We show them the evidence (of the Truth) but they always ignore it. 46 Say: Can ye see yourselves, if the punishment of Allah come upon you unawares or openly? Would any perish save wrongdoing folk? 47 We do not send the Envoys, except good tidings to bear, and warning; whoever believes and makes amends -- no fear shall be on them, neither shall they sorrow. 48 But those who cry lies to Our signs, them the chastisement shall visit, for that they were ungodly. 49 (O Muhammad!) Say: 'I do not say to you I have the treasures of Allah. Nor do I have knowledge of what is beyond the reach of human perception. Nor do I say to you: I am an angel. I only follow what is revealed to me.' Then ask them: 'Are the blind and the seeing alike?' Do you not then reflect? 50
