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 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 When they forgot (all) the advice that they had received, We granted them all means of happiness but they were left in despair when We suddenly took Our bounties back from them. 44 The origins of the unjust people were therefore cut off; and all praise is to Allah, Lord Of The Creation. 45 (Muhammad), ask them, "Have you ever considered that if God was to disable your hearing and vision and veil your hearts, could anyone besides Him restore them?" Look at how plainly We show them the evidence (of the Truth) but they always ignore it. 46 Say: "Think ye, if the punishment of Allah comes to you, whether suddenly or openly, will any be destroyed except those who do wrong? 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 And those who deny Our signs – the punishment will afflict them for their disobedience. 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
