Houseflies are known to have a unique feeding behavior. They do not consume solid food directly but instead feed on liquids. When they land on food, they secrete enzymes and saliva to break down the solids into a liquid form, which they then suck up. This process makes it impossible for a housefly to carry solid food away with it; any food it consumes has already been liquefied through digestion. Scientific Insight: - Houseflies primarily feed on liquids, including rotting organic matter, animal waste, sugary substances, and milk. Their saliva contains digestive enzymes that break down solid foods into liquids before they can ingest them. If a housefly takes something, it is already digested and in liquid form. This crucial detail was not understood in ancient times.

The Quran contains a verse that seemingly describes the behavior of houseflies in a way that matches our current scientific understanding, even though this knowledge was unknown at the time.

The verse states that if a housefly steals something, it cannot be recovered. This aligns with the modern understanding that a housefly can only consume digested food, which is already in liquid form. This "stolen" food cannot be retrieved because it has already been broken down by the fly's digestive enzymes. The phrase "Weak are the pursuer and the pursued" could be interpreted as a reference to the fact that the material the fly takes is already digested and, therefore, "weak" or altered, making it impossible to retrieve. The detail that houseflies can only feed on digested material was only confirmed recently, yet this knowledge is present in the Quran, highlighting the text's remarkable accuracy long before it was understood.
