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 So why did they not humbly plead when Our punishment came to them? But their hearts were hardened and the devil made all their deeds appear good to them! 43 When they had forgotten Our admonition, We granted them all that they desired; but just as they were rejoicing in what they were given, We seized them suddenly and they were plunged into despair. 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, "Have you considered: if the punishment of Allah should come to you unexpectedly or manifestly, will any be destroyed but the wrongdoing people?" 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 deny Our messages will be seized by nemesis for being disobedient. 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
