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 take it to Ourselves, taking little by little. 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 it is He who has loosed the winds, bearing good tidings before His mercy; and We sent down from heaven pure water 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 present the same phenomenon over and over again before them so that they may learn a lesson from it; but most people decline to adopt any other attitude than of disbelief and ingratitude. 50 Had it been Our Will, We could have sent a warner to every centre of population. 51 so do not yield to those who deny the truth, but strive with the utmost strenuousness by means of this [Quran, to convey its message to them]. 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 out of this [very] water has created man, and has endowed him with [the consciousness of] descent and marriage-tie: for thy Sustainer is ever infinite in His power. 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 We have sent you for no other reason but to be a bearer of glad news and warning. 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 Hence, place thy trust in the Living One who dies not, and extol His limitless glory and praise: for none is as aware as His creatures' sins as He 58 Who created the heavens and the earth and whatsoever is in-between them in six days, then He established Himself on the Throne - the Compassionate! so, concerning Him, ask any one informed. 59 And when it is said unto them: prostrate yourselves unto the Compassionate, they say: and what is the Compassionate? Shall we prostrate ourselves unto that which thou commandest us? And it increaseth in them aversion. ۩ 60
