And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 A token unto them is night. We strip it of the day, and lo! they are in darkness. 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the 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 overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. 40 And an Ayah (sign) for them is that We bore their offspring in the laden ship [of Nuh (Noah)]. 41 And We have created for them similar ships, in which they now ride. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 Unless by mercy from Us and as comfort for a while. 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 None of the signs of their Lord ever comes to them but they turn 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 await but one Shout, which will seize them while they dispute. 49 Therefore neither able to make a will, nor returning to their homes. 50
