And indeed, We sent Our messages unto people before thy time, [O Prophet,] and visited them with misfortune and hardship so that they might humble themselves: 42 Then why, when Our punishment came to them, did they not humble themselves? But their hearts became hardened, and Satan made attractive to them that which they were doing. 43 When they forgot (all) the advice that they had received, We granted them all means of happiness but they were left in despair when We suddenly took Our bounties back from them. 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 And We send not the messengers except as bringers of good tidings and warners. So whoever believes and reforms - there will be no fear concerning them, nor will they grieve. 48 But those who cry lies to Our signs, them the chastisement shall visit, for that they were ungodly. 49 Say: "I tell you not that with me are the treasures of Allah, nor do I know what is hidden, nor do I tell you I am an angel. I but follow what is revealed to me." Say: "can the blind be held equal to the seeing?" Will ye then consider not? 50
