Evil (sins and disobedience of Allah, etc.) has appeared on land and sea because of what the hands of men have earned (by oppression and evil deeds, etc.), that Allah may make them taste a part of that which they have done, in order that they may return (by repenting to Allah, and begging His Pardon). 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 So set thy purpose resolutely for the right religion, before the inevitable day cometh from Allah. On that day mankind will be sundered- 43 Whoever disbelieves - upon him is [the consequence of] his disbelief. And whoever does righteousness - they are for themselves preparing, 44 That He may reward those who have believed and done righteous deeds out of His bounty. Indeed, He does not like the disbelievers. 45 And of His signs is this: He sendeth herald winds to make you taste His mercy, and that the ships may sail at His command, and that ye may seek his favour, and that haply ye may be thankful. 46 And certainly We sent before you apostles to their people, so they came to them with clear arguments, then We gave the punishment to those who were guilty; and helping the believers is ever incumbent on Us. 47 It is God who sends forth the winds [of hope,] so that they raise a cloud - whereupon He spreads it over the skies as He wills, and causes it to break up so that thou seest rain issue from within it: and as soon as He causes it to fall upon whomever He wills of His servants - lo! they rejoice, 48 though before that, before it was sent down upon them, they were in despair. 49 Look then at the marks of Mercy of Allah; how He revives the earth after its death. He is the Reviver of the dead. He has power over all things. 50 But if We should send a [bad] wind and they saw [their crops] turned yellow, they would remain thereafter disbelievers. 51 So verily, you (O Muhammad SAW) cannot make the dead to hear (i.e. the disbelievers, etc.), nor can you make the deaf to hear the call, when they show their backs, turning away. 52 just as thou canst not lead the blind [of heart] out of their error: none canst thou make hear [thy call] save such as [are willing to] believe in Our messages, and thus surrender themselves unto Us. 53
