Do you not see how your Lord stretches the shadow? Had it been His will, He could have made it constant. Then He appointed the sun to be a guide to it; 45 then We withdrew it to Us, a gradual withdrawal. 46 It is He who has appointed the night a mantle for you and sleep for a rest. The day He has appointed for 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 That We may give life thereby to a dead land, and We give many beasts and men that We have created to drink thereof. 49 We have indeed turned it about them, so that they remember; yet most people refuse all except disbelief. 50 Had We wanted We could have sent a Prophet to every town. 51 So do not listen to unbelievers, and strive against them with greater effort. 52 ۞ It is He who released the two bodies of flowing water, one sweet and fresh and the other salty and bitter, and set up an insurmountable barrier between them. 53 And He it is Who has created man from the water, then He has made for him blood relationship and marriage relationship, and your Lord is powerful. 54 Yet they (the unbelievers) worship, other than Allah, that which can neither benefit nor harm them. Surely, the unbeliever is ever a partisan against his Lord. 55 We did not send you but as a bearer of glad tidings and as a 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 it is He who created the heavens and the earth and all that is between them in six Days [periods], then settled Himself on the throne -- the Gracious One. Ask any informed person about Him. 59 Yet when they [who are bent on denying the truth are told, "Prostrate yourselves before the Most Gracious" they are wont to ask, "And [who and] what is the Most Gracious? Are we to prostrate ourselves before whatever thou biddest us [to worship]?" - and so [thy call] but increases their aversion, ۩ 60
