Indeed We sent to nations before thee, and We seized them with misery and hardship that haply they might be humble; 42 if only, when Our might came upon them, they had been humble! But their hearts were hard, and Satan decked out fair to them what they were doing. 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 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: Can ye see yourselves, if the punishment of Allah come upon you unawares or openly? Would any perish save wrongdoing folk? 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 whereas those who give the lie to Our signs, chastisement will visit them for their transgression. 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
