And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 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 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 The origins of the unjust people were therefore cut off; and all praise is to Allah, Lord Of The Creation. 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 thou look ye now, were Allah's torment to come upon you on a sudden or openly, would there be destroyed any but the wrong-doers? 47 We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them neither shall they grieve. 48 But those who reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 49 Say, [O Muhammad], "I do not tell you that I have the depositories [containing the provision] of Allah or that I know the unseen, nor do I tell you that I am an angel. I only follow what is revealed to me." Say, "Is the blind equivalent to the seeing? Then will you not give thought?" 50
