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 withdraw it to Us a gradual concealed withdrawal. 46 And He it is Who made the night a covering for you, and the sleep a rest, and He made the day to rise up again. 47 And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky, 48 so that He may revive the dead land, and quench the thirst of many of His creatures from among beasts and men. 49 We have explained it to them in diverse ways, so that they may take heed, but most persist in their ingratitude. 50 And if We had willed, We would have raised up in each town a warner. 51 So obey not the disbelievers, but strive against them herewith with a great endeavour. 52 ۞ And it is He who hath mixed the two seas: this, sweet and thirst quenching; that, saltish and bitter; and hath placed between the twain a barrier and a great partition complete. 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 Allah, that which can neither benefit them nor hurt them; and the infidel is ever an aider of the devil against his Lord. 55 And We sent thee but as a bearer of glad tidings and warner. 56 Say, "I do not ask of you for it any payment - only that whoever wills might take to his Lord a way." 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 He Who created the heavens and the earth and all that is between, in six days, and is firmly established on the Throne (of Authority): Allah Most Gracious: ask thou, then, about Him of any acquainted (with such things). 59 But when they are told, 'Bow yourselves to the All-merciful,' they say, 'And what is the All-merciful? Shall we bow ourselves to what thou biddest us?' And it increases them in aversion. ۩ 60
