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 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 what they were reminded of; We opened unto them the gates of everything until; when they rejoiced in what they were given, We seized them suddenly, and behold, they were sore confounded. 44 So the people that committed wrong were eliminated. And praise to Allah, Lord of the worlds. 45 Say: "Think ye, if Allah took away your hearing and your sight, and sealed up your hearts, who - a god other than Allah - could restore them to you?" See how We explain the signs by various (symbols); yet they turn aside. 46 Say: 'What do you see yourselves then, if the punishment of Allah overtook you suddenly or openly, would any perish but the harmdoing nation' 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 deny Our messages will be seized by nemesis for being disobedient. 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
