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 made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 That they may eat of His fruit. And their hands have not produced it, so will they not 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 to them is the night: We draw forth from it the day, then lo! they are in the dark; 37 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 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 a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 We have created for them the like of it in which they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 Therefore neither able to make a will, nor returning to their homes. 50
