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 When the affliction decreed by Us befell them, they did not humble themselves, but rather their hearts hardened, for Satan had made all their doings seem fair to them. 43 But when they forgot the warning they had received, We opened to them the gates of all (good) things, until, in the midst of their enjoyment of Our gifts, on a sudden, We called them to account, when lo! they were plunged in despair! 44 The wrongdoers were thus annihilated. All praise be to God, the Lord of the Worlds. 45 Say, "Have you considered: if Allah should take away your hearing and your sight and set a seal upon your hearts, which deity other than Allah could bring them [back] to you?" Look how we diversify the verses; then they [still] 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 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 whereas those who give the lie to Our signs, chastisement will visit them for their transgression. 49 Say: "I tell you not that with me are the treasures of Allah, nor do I know what is hidden, nor do I tell you I am an angel. I but follow what is revealed to me." Say: "can the blind be held equal to the seeing?" Will ye then consider not? 50
