A Sign for them is the earth that is dead: We do give it life, and produce grain therefrom, of which ye do eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 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 for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 how the sun moves in its orbit and this is the decree of the Majestic and All-knowing God; 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 We have created for them the like of it in which 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 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 And there comes not to them a communication of the communications of their Lord but they turn aside from it. 46 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 And they add, "When is this promise [of resurrection] to be fulfilled? [Answer this] if you are men of truth!" 48 They do not await except one blast which will seize them while they are disputing. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
