And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may enjoy the fruits of this (artistry): It was not their hands that made this: will they not then give thanks? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left 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 it in phases till it returns like an old palmbranch. 39 It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law). 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 And We have created for them of the like thereunto whereon they ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 Unless by mercy from Us and as comfort 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 And whenever a sign comes to them from the signs of their Lord, they always 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 And they say: When will this threat come to pass, if you are truthful? 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 And they will not be able to make a disposition, nor to their family they return. 50
