Glorified is He who has made the night as day for them to seek livelihood and made the day for rest and stay. He has given them wings of flesh with which, at the time of need, they rise upwards for flying. They look like the ends of ears without feathers or bones. Of course, you can see the veins quite distinctly. They have two wings which are neither too thin so that get turned in flying, nor too thick so that they prove heavy. When they fly their young ones hold on to them and seek refuge with them, getting down when they get down and rising up when they rise. The young does not leave them till its limbs become strong, its wings can support it for rising up, and it begins to recognize its places of living and its interest. Glorified is He who creates everything without any previous sample by someone else.
