The Quran contains colossal amounts of knowledge. Many scholars of Tafseer (Exegesis) have attested to the unique knowledge encapsulated in the Quran.
Hadhrat Abdullah Bin Masood (Radhiyallahu Anhu states: Whosoever wishes to learn knowledge, then he should seek knowledge from the Quran.
Allamah Suyoothi (Rahmatullahi Alayhi), a famous Mufassir (exegete) and Muhaddith (expert in Hadeeth) states: The knowledge of the Quran and that which is deduced wherefrom is, a sea which has no shore
Qaadhi Abu Bakr Ibnul Arabi (Rahmatullahi Alayhi), a famous Mufassir (exegete) discusses the unique knowledge of the Quran and states: Indeed the Quran has seventy seven thousand four hundred and fifty branches (77, 450) of knowledge according to the number of words in the Quran. Each word contains four dimensional branches of knowledge which when multiplied, the total amount of branches of knowledge contained in the Quran is three hundred and nine thousand eight hundred (309, 800).
Each verse has the following four dimensions:
Qaadhi Abu Bakr Ibnul - Arabi (Rahmatullahi Alayh) further states that: This is a general figure without taking into consideration the unique syntaxical construction of the Quran. When that is taken into consideration, the amount of knowledge is infinite and is only known by Allah (Azza Wa Jalle)
The above statements clearly expounds the colossal and infinite knowledge contained in the Quran which we can never fully understand.

28. Social Science
This is the tip of the iceberg; the Quran contains much more knowledge.
Only recently Scientists have discovered the enormous scientific facts and secrets hidden in the Quran.

Our weak intellectual capacities in front of Allah (Subhanau Wa Taala)s knowledge is like a drop of water in the ocean. We can never equate our knowledge with that of the Quran since it contains such vast and infinite collections of knowledge.
