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 It is He who has appointed the night a mantle for you and sleep for a rest. The day He has appointed for rising. 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 That with it We may give life to a dead land, and slake the thirst of things We have created,- cattle and men in great numbers. 49 We have indeed turned it about amongst them, so that they may remember; yet most men refuse all but unbelief. 50 If We had so wished, We might have sent a warner into every town, 51 So do not listen to unbelievers, and strive against them with greater effort. 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 But they worship rather than Allah that which does not benefit them or harm them, and the disbeliever is ever, against his Lord, an assistant [to Satan]. 55 We have sent you only as a bearer of glad tidings and as a warner. 56 Tell them, "I do not ask of you any recompense for this work: I only ask of the one, who will, to adopt the way of 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 He who has created the heavens and the earth and all that is between them in six aeons, and is established on the throne of His almightiness; the Most Gracious! Ask, then, about Him, [the] One who is [truly] aware. 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
