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 But when misfortune befell them from Us why did they not humble themselves? Their hearts had hardened and Satan had made their deeds seem fair to them. 43 But when they neglected that with which they had been admonished, We opened for them the doors of all things, until when they rejoiced in what they were given We seized them suddenly; then lo! 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: "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: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?" 47 And We did not send Noble Messengers except as Heralds of glad tidings and warnings; so upon those who accept faith and reform themselves, shall be 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 (O Muhammad!) Say: 'I do not say to you I have the treasures of Allah. Nor do I have knowledge of what is beyond the reach of human perception. Nor do I say to you: I am an angel. I only follow what is revealed to me.' Then ask them: 'Are the blind and the seeing alike?' Do you not then reflect? 50
