Have you not seen how your Lord spread the shadow. If He willed, He could have made it still then We have made the sun its guide [i.e. after the sunrise, it (the shadow) squeezes and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sun light, there would have been no shadow]. 45 Then We withdraw it unto Us, a gradual withdrawal? 46 It is He who appointed the night for you to be a garment and sleep for a rest, and day He appointed for a rising. 47 It is He who sends the winds to you with the glad news of His mercy and who sends purifying rain from the sky 48 so that We might revive a dead land, and give to drink of it, of that We created, cattle and men a many. 49 We present the same phenomenon over and over again before them so that they may learn a lesson from it; but most people decline to adopt any other attitude than of disbelief and ingratitude. 50 If We willed, We could raise up a warner in every village. 51 Se obey not thou the infidels, but strive against them therewith with a great striving. 52 ۞ And He it is Who has made two seas to flow freely, the one sweet that subdues thirst by its sweetness, and the other salt that burns by its saltness; and between the two He has made a barrier and inviolable obstruction. 53 It is He who has created human beings from water and He has granted them the ties of blood as well as marriage. Your Lord is all powerful. 54 And they serve besides Allah that which neither profits them nor causes them harm; and the unbeliever is a partisan against his Lord. 55 Yet We have not sent you but to give good tidings and to warn. 56 Say: 'I do not ask of you a wage for this, except for him who wishes to take to his Lord a way.' 57 And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants, 58 He who created the heavens and the earth and what is between them in six days and then established Himself above the Throne - the Most Merciful, so ask about Him one well informed. 59 When it is said to them: 'Prostrate yourselves before the Merciful', they ask: 'And what is the Merciful? Shall we prostrate ourselves to whatever you bid us' And it increases their aversion. ۩ 60
