Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 Why did they not submit themselves (to God) when Our torment struck them. Instead, their hearts were hardened and Satan made their evil deeds seem attractive to them. 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 were the wicked people rooted out of existence to the last. All praise be to God, the Lord of all 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: "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 do not send the Envoys, except good tidings to bear, and warning; whoever believes and makes amends -- no fear shall be on them, neither shall they sorrow. 48 But those who cry lies to Our signs, them the chastisement shall visit, for that they were ungodly. 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
