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 (Muhammad), tell them, "Travel through the land to see how terrible was the end of those who lived before. Many of them were pagans. 42 Set, then, thy face steadfastly towards the one ever-true faith, ere there come from God a Day [of reckoning - the Day] which cannot be averted. On that Day all will be sundered: 43 Those who disbelieve will be charged for their disbelief, while the righteous are making provision for themselves 44 That He may reward out of His bounty those who believe and do good works. Lo! He loveth not the disbelievers (in His guidance). 45 Among His Signs is this, that He sends the Winds, as heralds of Glad Tidings, giving you a taste of His (Grace and) Mercy,- that the ships may sail (majestically) by His Command and that ye may seek of His Bounty: in order that ye may be grateful. 46 We sent Messengers before you to their respective nations, and they brought Clear Signs to them. Then We took vengeance upon those who acted wickedly. It was incumbent on Us to come to the aid of the believers. 47 It is God who sends out the winds so that they raise the clouds. Then He spreads them in the sky as He wills and places them layer upon layer and you see the rain issuing forth from their midst. When He causes it to fall on whichever of His servants He pleases, behold! they rejoice; 48 though before that, before it was sent down upon them, they were in despair. 49 Look then at the signs of Allah's mercy, how He gives life to the earth after its death, most surely He will raise the dead to life; and He has power over all things. 50 But if We loose a wind, and they see it growing yellow, they remain after that unbelievers. 51 And verily, thou canst not make the dead hear: and [so, too,] thou canst not make the deaf [of heart] hear this call when they turn their backs [on thee] and go away, 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
