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 Then when they forgot that whereof they were reminded We opened upon them the doors of everything, until when they boasted of that which they were given, We laid hold of them on a sudden, and lo! they were dumbfounded. 44 Thus the last remnant of those wrongdoing people was cut off. All praise is for Allah, the Lord of the entire universe, (for having punished them so). 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 punishment of Allah should come to you unexpectedly or manifestly, will any be destroyed but the wrongdoing people?" 47 We send forth Our Messengers only to give glad tidings to mankind and to warn them. Those who believe and mend their ways shall have nothing to fear or to be saddened. 48 But those who cry lies to Our signs, them the chastisement shall visit, for that they were ungodly. 49 Say (O Muhammad, to the disbelievers): I say not unto you (that) I possess the treasures of Allah, nor that I have knowledge of the Unseen; and I say not unto you: Lo! I am an angel. I follow only that which is inspired in me. Say: Are the blind man and the seer equal? Will ye not then take thought? 50
