Art thou not aware of thy Sustainer [through His works]? - how He causes the shadow to lengthen [towards the night] when, had He so willed, He could indeed have made it stand still: but then, We have made the sun its guide; 45 Then We draw it back to Us, withdrawing it little by little. 46 And it is He Who made the night a veil for you, and the sleep a rest, and made the day for getting up. 47 It is He who sends the winds with auspicious news in advance of His benevolence; and We send pure water down 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 certainly We have repeated this to them that they may be mindful, but the greater number of men do not consent to aught except denying. 50 And if We had willed, We could have sent into every city a warner. 51 So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour, with it (the Quran). 52 ۞ And it is He, Who has let loose the two seas, one palatable and sweet, the other bitter and saltish, and there is a partition between them, which is an insurmountable barrier. 53 And He it is Who hath created man from water, and hath appointed for him kindred by blood and kindred by marriage; for thy Lord is ever Powerful. 54 Yet they worship, instead of Allah, those who can neither benefit them nor harm them: more than this, the disbeliever has become a helper of every rebel against his Lord. 55 But thee We only sent to give glad tidings and admonition. 56 Tell them: "I do not ask any recompense of you for this other than (urging) whoever likes may take the way to his Lord." 57 Also trust in the Living One who never dies and glorify Him with His praise. He has sufficient knowledge of the sins of His servants. 58 He who created the heavens and the earth and what is between them in six days and then established Himself above the Throne - the Most Merciful, so ask about Him one well informed. 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
