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 produced therein grains from which they eat and established therein gardens of palms trees and vineyards and have made streams flow therein 34 so that they might eat of its fruit and the labor of their hands. Will they not give 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 the night is another Sign for them. We strip the day from it and they become 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 measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 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 Another sign for them is that We carried their offspring in the laden Ark. 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 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 never came an Ayah from among the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of their Lord to them, but they did turn away from it. 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 They will have no time to make a will, nor shall they return to their own people. 50
