In social matters, the patterns are more complicated to experiment and to conclude. In spite of the good progress that we may claim, we are far beyond, and are still inexperienced beginners. Most, if not all, of what we unanimously agree upon today, was preached to our ancestors by a humanity leader who was tutored by a prophet or was himself a prophet. What we experiment ourselves are just confirmations to what was revealed and preached earlier.
The Koran offers an easy but definite guide to social prosperity and happiness, and stands unchallenged and incomparable as the only intact Holy Book since the creation of Adam. It documents all social patterns that humanity would need for prosperous and happy life journey on earth and joyful eternal destination in the life after. These patterns stand perfect, either to be embraced or to be derived.
