There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 And We have placed in it gardens of dates and grapes, and We have made springs of water in it. 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 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 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, the All-Knowing; 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 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 And if We should will, We could drown them; then no one responding to a cry would there be for them, nor would they be saved 43 But (by) mercy from Us and for enjoyment till a 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 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 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 also say, 'When shall this promise come to pass, if you speak truly?' 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they will not be able to make a will or return to their families. 50
