There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 So that they may eat from its fruits, whereas they are not manufactured by their hands! 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 for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-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 allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them the like of it, what they will ride on. 42 and if We will, We drown them, then none have they to cry to, neither are they delivered, 43 save as a mercy from Us, and enjoyment 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 it is said to them: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain 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 Then they cannot make bequest, nor can they return to their own folk. 50
