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 So set thy purpose resolutely for the right religion, before the inevitable day cometh from Allah. On that day mankind will be sundered- 43 Whosoever disbelieveth, on him is his infidelity, and those who work righteously are preparing for themselves. 44 For then He will reward out of His bounty those who believe and do good deeds; He does not love those who reject the truth. 45 Some evidence of His existence is His sending the glad-news-bearing winds so that He would let you to receive His mercy, cause the ships to sail by His command, and let you seek His favor so that perhaps you would give Him thanks. 46 Verily We sent many apostles before you to their people, who brought clear signs with them. Then We retributed those who were sinful. It is a duty incumbent on Us to help the believers. 47 It is Allah Who sends the winds raising the clouds – therefore spreads them in the sky as He wills and shatters them – so you see the rain dropping from inside it; so when He delivers it upon whomever He wills among His bondmen, thereupon they rejoice. 48 Though they were before this, before it was sent down upon them, confounded in sure despair. 49 Look at the traces of the mercy of God, how He has revived the dead earth. God revives the dead; He has power over all things. 50 And if We sent a wind and they beheld it yellow, they verily would still continue in their disbelief. 51 For verily thou (Muhammad) canst not make the dead to hear, nor canst thou make the deaf to hear the call when they have turned to flee. 52 Nor do you guide the blind out of their error; you only make those hear who believe in Our signs, so they have submitted. (The disbelievers are referred to as blind.) 53
