Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 Yet why did they not, when Our punishment came to them, humble themselves? But their hearts hardened and the Shaitan made what they did fair-seeming to them. 43 So when they forgot the advices made to them, We opened the gates of all things for them; to the extent that when they were rejoicing for what they had received, We seized them suddenly, hence they remained dejected. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 Say, "If God should take away your hearing and your sight and seal your hearts, who is the deity who could restore it to you save God?" See how We explain the signs to them in diverse ways, yet they turn away. 46 Say: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 We did not send the Messengers for any other reason than to bring (people) the glad news (of God's mercy) and to warn (them of the torment brought on by disobedience to God). Whoever accepts the faith and lives a righteous life will have nothing to fear, nor will he be grieved. 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
