There is a sign in the dead earth for them which We quicken, and produce from it grain which they eat. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what they do not know. 36 And there is a sign in the night for them. We strip off the day from it and they are left 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 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 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 And We created for them from the likes of it that which they ride. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 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 None of the signs of their Lord ever comes to them but they turn away from it. 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 And they say, "When is this promise, if you should be truthful?" 48 They must be waiting for but one single blast, which will overtake them while they are still disputing. 49 then they will not be able to make any testament, nor will they return to their people. 50
