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 Yet why did they not, when Our punishment came to them, humble themselves? But their hearts hardened and the Shaitan made what they did fair-seeming to them. 43 And when they had forgotten that with which they have been admonished, We opened the gates of everything to them, until just as they were rejoicing in what they were given, We suddenly seized them and they were in utter despair. 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher of 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 Tell them, "Have you considered that if God's torment was to befall you suddenly or in public, would anyone else be destroyed except the unjust?" 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 reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 49 Say [O Prophet]: "I do not say unto you, 'God's treasures are with me,'; nor [do I say,] 'I know the things that are beyond the reach of human perception'; nor do I say unto you, 'Behold, I am an angel': I but follow what is revealed to me." Say: "Can the blind and the seeing be deemed equal? Will you not, then, take thought?" 50
