The bee assimilates juices of various kinds of flowers and fruit and forms within its body the honey, which it stores in its cells of wax. Only a couple of centuries ago man came to know that honey comes from the belly of the bee. This fact was mentioned in the Qur'an 1,400 years ago in the following verse:
"There issues from within their bodies a drink of varying colours, wherein is healing for men." [Al-Qur'an 16:69]
We are now aware that honey has a healing property and also a mild antiseptic property. The Russians used honey to cover their wounds in World War II. The wound would retain moisture and would leave very little scar tissue. Due to the density of honey, no fungus or bacteria would grow in the wound. A person suffering from an allergy of a particular plant may be given honey from that plant so that the person develops resistance to that allergy. Honey is rich in fructose and vitamin K. Thus the knowledge contained in the Qur'an regarding honey, its origin and properties, was far ahead of the time it was revealed.
