Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 But when misfortune befell them from Us why did they not humble themselves? Their hearts had hardened and Satan had made their deeds seem fair to them. 43 Then, when they had forgotten all that they had been told to take to heart, We threw open to them the gates of all [good] things until - even as they were rejoicing in what they had been granted - We suddenly took them to task: and lo! they were broken in spirit; 44 Thus the last remnant of those wrongdoing people was cut off. All praise is for Allah, the Lord of the entire universe, (for having punished them so). 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: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 We send forth Our Messengers only to give glad tidings to mankind and to warn them. Those who believe and mend their ways shall have nothing to fear or to be saddened. 48 And those who deny Our signs – the punishment will afflict them for their disobedience. 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
