For Men of Understanding One of the purposes why the Qur'an was revealed is to summon people to think about creation and its works. When a person examines his own body or any other living thing in nature, the world or the whole universe, in it he sees a great design, art, plan and intelligence. All this is evidence proving Allah's being, unit, and eternal power. For Men of Understanding was written to make the reader see and realise some of the evidence of creation in nature. Many living miracles are revealed in the book with hundreds of pictures and brief explanations.
Microbes intrude into our body and reproduce rapidly.
The body, however, has a mechanism that combats them. This system proves that the human body is the outcome of a unique design. In other words, the human body is an evidence of the flawless creation of God. The progress of science makes it clear that living beings have an extremely complex structure and an order too perfect to have come into being by coincidence. This is evidence to the fact that living beings are created by an All-Powerful Creator with superior knowledge.
