Surah 27. An-Naml, Ayah 20

Solomon was no idle or easy-going king. He kept all his organisation strictly up to the mark, both his armies literally and his forces (metaphorically). His most mobile arm was the Birds, who were light on the wing and flew and saw everything like efficient scouts. One day he missed the Hoopoe in his muster. The Hoopoe is a light, graceful creature, with elegant plumage of many colours, and a beautiful yellow crest on his head, which entities him to be called a royal bird.
