Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 35 Glory be to Him, Who has created all the pairs of that which the earth produces, as well as of their own (human) kind (male and female), and of that which they know not. 36 And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 And have created for them of the like thereof whereon they ride. 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 43 unless it be a mercy from us, and as an enjoyment for a season. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 Indeed, not one of your Lord's signs comes to them without their turning 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 ye are truthful? 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 So they shall not be able to make a bequest, nor shall they return to their families. 50
