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 (as the sun climbs up), We roll it up little by little towards Ourselves. 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 sent the winds giving glad tidings before His mercy; and We sent down purifying water from the sky. 48 so that We might revive a dead land, and give to drink of it, of that We created, cattle and men a many. 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 And had We willed, We would have raised a warner in every town. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 52 ۞ It was He who let forth the two seas, this one is palatably sweet and this salt, a bitter taste, and He set a barrier between them, and a refuge which is forbidden. 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, apart from God, what neither profits them nor hurts them; and the unbeliever is ever a partisan against his Lord. 55 O Muhammad, We have sent you only to proclaim good tidings and to give warning. 56 Say: I ask of you no reward for this, save that whoso will may choose a way unto 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 and then He established His domination over the Throne. He is the Beneficent God. Refer to Him as the final authority. 59 When it is said to them: 'Prostrate yourselves before the Merciful', they ask: 'And what is the Merciful? Shall we prostrate ourselves to whatever you bid us' And it increases their aversion. ۩ 60
