How did Mohammad (pbuh) know about the 20th century Scientific fact of the Bee Kingdom? Allah (SWT) is telling us that the Bee can produce different food! This is true since the Bee has a unique stomach that capable of producing food (honey) that is different in color and taste. Also, Allah (SWT) is referring to the bees in the feminine instead of muscular verbiage as in the Arabic word "Koolie" means eat and "fas-lookie" which means follow the way.

This paragraph was obtained from the Internet regarding the Honey Bee and how it produces different types of honey: " There are as many flavors of honey as there are flowers. In early summer we get honey from wild berries and locust trees. The main honey flow occurs up here in teh North during July, and we harvest a delicious light honey made from the blossoms of clover, alfalfa,and wild flowers. As the season progresses, the later flowers, goidenrod and aster, darken the color and make the flavor more pronounced. Honey can be as dark as molasses, as those who know buckwheat honey can attest. Its dark color and distinctive flavor cannot be mistaken. If one type of flower predominates in an area, the honey will have its flavor. Most of you have probably seen orange blossom, tupelo, or sourwood honey for sale. Generally, the lighter the honey, the milder is its flavor and the better it is for general cooking."
