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 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 He who disbelieves will suffer the consequence of it and he who acts righteously, they will pave the way for their own good 44 So that He shall recompense those who believe and work righteous works out of His grace; verily He loveth not the infidels. 45 And of His signs is that He sendeth winds heralding rain and that He may make you taste of His mercy, and that the ships may sail at His command and that ye may seek His grace, and that haply ye may return 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 Allah is He Who sends the winds, so they raise clouds, and spread them along the sky as He wills, and then break them into fragments, until you see rain drops come forth from their midst! Then when He has made them fall on whom of His slaves as He will, lo! they rejoice! 48 Even though, before they received (the rain) - just before this - they were dumb with 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 send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow, behold, they then after their being glad, would become unthankful (to their Lord Allah as) disbelievers. 51 You cannot make the dead to listen nor the deaf hear the call when they have turned back and retreated, 52 Nor canst thou guide the blind out of their error. Thou canst make none to hear save those who believe in Our revelations so that they surrender (unto Him). 53
