Part I: "The Four Animals Emphasised in the Qur’an" - The Fly

O mankind! A likeness has been made, so listen to it carefully. Those you call upon apart from Allah are not even able to create a single fly, even if they were to join together to do it. And if a fly steals something away from them, they cannot get it back from it. How feeble are both the seeker and the sought! They do not measure Allah with His true measure. Allah is All-Strong, Almighty. (Surat al-Hajj: 73-74)

Panoramic sight from thousands of lenses

The hexagonal shaped lenses constituting the eyes of a fly provide a much larger area of vision than an ordinary lens does. In some flies, the number of these lenses may sometimes be as many as 5,000. Additionally, the spherical structure of the eye also enables the fly to see its back, and thus gives it a great advantage over its enemies.

The absorbent pump of the fly: Proboscis

Another specific feature of flies is the way they digest food. Unlike many other living organisms, flies digest food not in their mouth, but outside their bodies. They pour a special liquid over the food by means of their proboscis, which puts the food in the proper degree of consistency for absorption. Then the fly absorbs the food with the absorbent pumps in its throat.
