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 hold it in hand for a brief grasp. 46 And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the 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 bring to life thereby a dead land and give it as drink to those We created of numerous livestock and men. 49 And indeed We kept cycles of water among them that they may remember; so most men did not accept, except to be ungrateful. 50 And if We had pleased We would certainly have raised a warner in every town. 51 So do not obey the disbelievers, and strive against them with the Qur'an 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 the human being from water to have relationships of both lineage and wedlock. Your Lord has all power. 54 And yet, some people worship, instead of God, things that can neither benefit them nor harm them: thus, he who denies the truth does indeed turn his back on his Sustainer! 55 And We have not sent you, [O Muhammad], except as a bringer of good tidings and a warner. 56 Say: "No reward do I ask of you for this (that which I have brought from my Lord and its preaching, etc.), save that whosoever wills, may take a Path to 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 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 And when it is said to them, "Prostrate to the Most Merciful," they say, "And what is the Most Merciful? Should we prostrate to that which you order us?" And it increases them in aversion. ۩ 60
