And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 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 So, when they forgot (the warning) with which they had been reminded, We opened to them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them to punishment, and lo! They were plunged into destruction with deep regrets and sorrows. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord 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 Say, “What is your opinion – if the punishment of Allah were to come upon you suddenly or openly (with forewarning), who would be destroyed except the disbelieving 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 belie Our verses, punishment shall touch them for their misdeeds. 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
