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 did not make it; will they not then be grateful? 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 And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 The sun runs to its fixed resting place; that is the decree of the Almighty, the Knower. 38 and [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 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 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 And We created for them from the likes of it that which they ride. 42 And if We will, We shall drown them, and there will be no shout (or helper) for them (to hear their cry for help) nor will they be saved. 43 Unless by mercy from Us and as comfort for a while. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 Indeed, not one of your Lord's signs comes to them without their turning away 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 say: When will this threat come to pass, if you are truthful? 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
