We have sent already unto peoples that were before thee, and We visited them with tribulation and adversity, in order that they might grow humble. 42 When the affliction decreed by Us befell them, they did not humble themselves, but rather their hearts hardened, for Satan had made all their doings seem fair to them. 43 But when they forgot the warning they had received, We opened to them the gates of all (good) things, until, in the midst of their enjoyment of Our gifts, on a sudden, We called them to account, when lo! they were plunged in despair! 44 and [in the end,] the last remnant of those folk who had been bent on evildoing was wiped out. For all praise is due to God, the Sustainer of all the worlds. 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: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust people? 47 And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor 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
