Evil has spread over the land and the sea because of human deeds and through these God will cause some people to suffer so that perhaps they will return to Him. 41 Say, [O Muhammad], "Travel through the land and observe how was the end of those before. Most of them were associators [of others with Allah]. 42 Therefore in purity set your face to the religion, before there comes from Allah a Day that cannot be turned back. On that Day mankind will be separated. 43 Whoever disbelieves - upon him is [the consequence of] his disbelief. And whoever does righteousness - they are for themselves preparing, 44 so that He will recompense those who believe and do righteous deeds from His bounty. He does not love the unbelievers. 45 for among His wonders is this: He sends forth [His messages as He sends forth] the winds that bear glad tidings, so that He might give you a taste of His grace [through life-giving rains,] and that ships might sail at His behest, and that you might go about in quest of some of His bounties, and that you might have cause to be grateful. 46 And We have already sent messengers before you to their peoples, and they came to them with clear evidences; then We took retribution from those who committed crimes, and incumbent upon Us was support of the believers. 47 It is God who sends the winds to raise the clouds. He spreads them in the sky as He wants, then He intensifies them, and then you can see the rain coming down from the cloud. When He sends it down upon whichever of His servants He wants, they rejoice 48 Although they were, before it was sent down upon them - before that, in despair. 49 Behold, then, [O man,] these signs of God's grace - how He gives life to the earth after it had been lifeless! Verily, this Selfsame [God] is indeed the One that can bring the dead back to life: for He has the power to will anything! 50 And if We sent a wind and they beheld it yellow, they verily would still continue in their disbelief. 51 Thou shalt not make the dead to hear, neither shalt thou make the deaf to hear the call when they turn about, retreating. 52 Nor can you make the blind see the way when they have gone astray. You can make none hear except those who believe Our signs and have come to submission. 53
