Have you not seen that your Lord increases the shadow. Had He wanted He would have made it stationary], and has made the sun their guide. 45 then We withdrew it to Us, a gradual withdrawal. 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 sendeth the winds, glad tidings heralding His mercy, and We send down purifying water 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 And verily We have repeated it among them that they may remember, but most of mankind begrudge aught save ingratitude. 50 Now had We so willed, We could have [continued as before and] raised up a [separate] warner in every single community: 51 Se obey not thou the infidels, but strive against them therewith with a great striving. 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 And it is He who created the human from water and gave him kindred of blood and of marriage. Your Lord is the Powerful. 54 And yet they worship besides God what cannot bring them gain or do them harm. The unbeliever has always been an auxiliary against his Lord. 55 We did not send you but as a bearer of glad tidings and as a warner. 56 Say: "For this, no reward do I ask of you - [no reward] other than that he who so wills may unto his Sustainer find 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 Who created the heavens and the earth and all that is between them in six Days, then He mounted the Throne. The Beneficent! Ask anyone informed concerning 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
