There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 So that they may eat from its fruits, whereas they are not manufactured by their hands! So will they not be grateful? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, they are in darkness. 37 The sun runs to its fixed resting place; that is the decree of the Almighty, the Knower. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 and We have created for them the like of it whereon they ride; 42 and [that,] if such be Our will, We may cause them to drown, with none to respond to their cry for help: and [then] they cannot be saved, 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 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 yet never any sign of the signs of their Lord comes to them, but they are 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 come to pass, if what you say is true?" 48 They do not await except one blast which will seize them while they are disputing. 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
