Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 And the Moon,- We have measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 39 It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 And when it is said to them, “Beware of what is before you and what is behind you, in the hope of your gaining mercy”, they turn away! 45 and no message of their Sustainer's messages ever reaches them without their turning away from it. 46 And when it is said to them: “Spend (in the Way of Allah) out of the sustenance that Allah has provided you,” the unbelievers say to the believers: “Shall we feed him whom, Allah would have fed, had He so wished?” Say: “You are in evident error.” 47 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 and so [sudden will be their end that] no testament will they be able to make, - nor to their own people will they return! 50
