Or do you think that most of them hear or understand? They are only like cattle; nay,— they are even farther astray from the Path. (i.e. even worst than cattle). (44) Have you not seen how your Lord spread the shadow. If He willed, He could have made it — still — But We have made the sun its guide [i.e. after the sunrise, the shadow shrinks and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sunlight, there would have been no shadow] (45) Then We withdraw it to Us a gradual concealed withdrawal. (46) And it is He Who makes the night a covering for you, and the sleep (as) a repose, and makes the day Nushûr (i.e. getting up and going about here and there for daily work, after one's sleep at night or like resurrection after one's death). (47) And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky. (48) That We may give life thereby to a dead land, and We give to drink thereof many of the cattle and men that We had created. (49) And indeed We have distributed it (rain or water) amongst them in order that they may remember (the Grace of Allâh), but most men (refuse to accept the Truth or Faith and) accept nothing but disbelief or ingratitude. (50) And had We willed, We would have raised a warner in every town. (51) So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour, with it (the Qur'ân). (52) And it is He Who has let free the two seas (kinds of water), one palatable and sweet, and the other salt and bitter, and He has set a barrier and a complete partition between them. (53) And it is He Who has created man from water, and has appointed for him kindred by blood, and kindred by marriage. And your Lord is Ever All-Powerful to do what He wills. (54) And they (disbelievers, polytheists) worship besides Allâh, that which can neither profit them nor harm them, and the disbeliever is ever a helper (of the Satan) against his Lord. (55)
