Have you not considered (the work of) your Lord, how He extends the shade? And if He had pleased He would certainly have made it stationary; then We have made the sun an indication of it 45 Then We withdraw it to Us a gradual concealed 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 And He it is Who sends the winds as heralds of glad tidings, going before His mercy, and We send down pure water from the sky,- 48 so that He may revive the dead land, and quench the thirst of many of His creatures from among beasts and men. 49 And We distribute it among them in various ways that they may ponder and reflect; yet most men disdain everything but denial and thanklessness. 50 And if We had willed, We would have raised up in each town a warner. 51 So obey not the disbelievers, but strive against them herewith with a great endeavour. 52 ۞ And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition. 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 worship such, other than Allah, which neither benefit nor hurt them; and the disbeliever helps the devil instead of his Lord. 55 And We have not sent you but as a giver of good news and as a warner. 56 Tell them, "I do not ask of you any recompense for this work: I only ask of the one, who will, to adopt the way of his Lord. 57 And trust thou in the Living One who dieth not, and hallow His praise; it sufficeth that He of the sins of His bondmen is Aware. 58 Who created the heavens and the earth and what is between them in six periods, and He is firmly established on the throne of authority; the Beneficent Allah, so ask respecting it one aware. 59 When they are told to prostrate themselves before the Beneficent God, they say, "Who is the Beneficent God? Why should we prostrate ourselves before the one whom you have commanded us to?" This only increases their rebelliousness. ۩ 60
