And a sign unto them is the dead land. We quicken it and thereout We bring forth grain, so that thereof they eat. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 Glory be to Him, Who has created all the pairs of that which the earth produces, as well as of their own (human) kind (male and female), and of that which they know not. 36 And a sign for them is the night. We remove from it [the light of] day, so they are [left] in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 and [that,] if such be Our will, We may cause them to drown, with none to respond to their cry for help: and [then] they cannot be saved, 43 except through Our Mercy and as enjoyment for awhile. 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 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 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 will this promise be fulfilled, if ye are truthful? 48 They await just one scream, which will overcome them while they are involved in worldly disputes. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
