And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give thanks? 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-knowing. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 And a sign for them is that We carried their seed in the laden ship, 41 We have created for them the like of it in which they ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 except through Our Mercy and as enjoyment for awhile. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 None of the signs of their Lord ever comes to them but they turn away from it. 46 And when it is said to them: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 And they say, “When will this promise be fulfilled, if you are truthful?” 48 They await only but a single Saihah (shout, etc.), which will seize them while they are disputing! 49 Then they will not be able to make a will or return to their families. 50
