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 Our Torment reached them, why then did they not believe with humility? But their hearts became hardened, and Shaitan (Satan) made fair-seeming to them that which they used to do. 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 Thus, the transgressing people were destroyed. It is only God, the Lord of creation who deserves all praise. 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 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 But those who deny Our verses - the punishment will touch them for their defiant disobedience. 49 Tell them: "I do not say that I possess the treasures of God, or have knowledge of the Unknown, or that I am an angel. I only follow what is sent down to me." And say: "How can a blind man and a man who can see, be alike? Will you not reflect?" 50
