Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 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 All glory to Him who created pairs of everything that grows from the earth, and out of themselves, and other 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 the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law). 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 and then created for them other vessels like those on which they ride. 42 And if We will, We can drown them, so there would be no help in their distress, nor would they be saved. 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 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 Never does any Sign of their Lord come to them, but they turn away from it. 46 And when it is said to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but 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
