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 That they may eat of the fruit thereof, and their hands did not make it; will they not then 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 [of Our sway over all that exists] they have a sign in the night: We withdraw from it the [light of] day - and lo! they are 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 measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 39 It is not permitted to the sun that it should overtake the moon, nor can the night outstrip the day: each in an orbit, they float. 40 That We bore their progeny in the laden ark is a sign for them; 41 and We have created for them the like of it whereon they ride; 42 And if We will, We shall drown them, and there will be no shout (or helper) for them (to hear their cry for help) nor will they be saved. 43 But (by) mercy from Us and for enjoyment till a time. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 46 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 And they say: when will this promise be fulfilled if ye say sooth? 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
