Bismillah hir Rahman nir Rahim.
What is meant by inspiration here is guidance. The bee is guided to make its home in the mountains, in trees and in structures erected by man. The bee’s home is a solid structure, with its hexagonal shapes and interlocking forms there is no looseness in its combs. Then Allah decrees that the bee will have permission to eat from all fruits and to follow the ways which Allah has made easy for it, wherever it wants to go in the vast spaces of the wilderness, valleys and high mountains. Then each bee comes back to its hive without swerving to the right or left, it comes straight back to its home where its offspring and honey are. It makes wax from its wings, and regurgitates honey from its mouth, and lays eggs from its rear, then the next morning it goes out to the fields again.
(There comes forth from their bellies, a drink of varying colors, wherein is healing for men.) ﴿meaning, honey, that is ﴾white, yellow, red, or of other good colors, depending on the different things that the bees eat.(in which there is a cure for men.) meaning there is a cure in honey for diseases that people suffer from.
(There is indeed a sign in that for people who reflect.) meaning in the fact that Allah inspires this weak little creature to travel through the vast fields and feed from every kind of fruit, then gather it for wax and honey, which are some of the best things, in this is a sign for people who think about the might and power of the bee’s Creator Who causes all of this to happen. From this they learn that He is the Initiator, the All-Powerful, the All-Wise, the All-Knowing, the Most Generous, the Most Merciful.
