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 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Glory be to Him, who created all the pairs of what the earth produces, and of themselves, and of what they know not. 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 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 and We have created for them the like of it whereon they ride; 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 Except as a mercy from Us and provision for a time. 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 And no sign comes to them from the signs of their Lord except that they are from it turning away. 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They await but one Shout, which will seize them while they dispute. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
