For Men of Understanding was written to make the reader see and realize some ofthe evidence of Creation in nature. Many living miracles are revealed in the book with hundreds of pictures and brief explanations. Every bit of beauty we see around us is ultimately destined to vanish. The brevity of life, mortality, and coming into the world only once are facts of the utmost importance for a person. Up to a certain age, a person may not realize this fact, but the moment he does, he has to review his entire life and rearrange it according to what Allah asks of him.
Life is short but the human soul lives for eternity.
A life so short has no worth besides the eternal one. Unquestionably it is unwise to forsake an eternal life for a little enjoyment in this world. Those who turn away from Allah's verses and deny their Creator will never prosper in the Hereafter. So, what is incumbent upon one is to immediately turn back from the path that leads to destruction and submit one s whole self to Allah. Otherwise, he is destined to suffer tremendous regret.
