See note [39] on 21:30 . The term dabbah denotes every corporeal being endowed with both life and spontaneous movement; hence, in its widest sense, it comprises the entire animal world, including man.
Cf. xxi. 30, n. 2691. Protoplasm is the basis of all living matter, and "the vital power of protoplasm seems to depend on the constant presence of water".
The creeping things include worms and lowly forms of animal life as well as reptiles (like snakes), centipedes, spiders, and insects. Where these have legs they are small, and the description of creeping or crawling is more applicable to them than that of walking. Fishes and sea-animals generally cannot be said to walk: their swimming is like "creeping on their bellies". Two-legged animals include birds and man. Most of the mammals walk on four legs. This includes the whole of the animal world.
In Allah's Will and Plan, the variety of forms and habits among animals is adapted to their various modes of life and stages of biological development.
