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 draw it in towards Ourselves,- a contraction by easy stages. 46 And He it is Who maketh night a covering for you, and sleep repose, and maketh day a resurrection. 47 And He it is Who sends the winds as good news before His mercy; and We send down pure water from the cloud, 48 That We may bring to life thereby a dead land and give it as drink to those We created of numerous livestock and men. 49 And indeed, many times have We repeated [all] this unto men, so that they might take it to heart: but most men refuse to be aught but ingrate. 50 Now had We so willed, We could have [continued as before and] raised up a [separate] warner in every single community: 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 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 And it is He who hath created man from water, and then made for him kinship by blood and marriage. And thy Lord is ever potent. 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 And We sent thee but as a bearer of glad tidings and warner. 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 Put your trust in the One who is the Ever-Living [God], who never dies, and glorify Him with His praise. He is fully aware of the sins of His servants; 58 He who has created the heavens and the earth and all that is between them in six aeons, and is established on the throne of His almightiness; the Most Gracious! Ask, then, about Him, [the] One who is [truly] 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
