The words “Water is the main component of organic matter. 50-90% of the weight of living things consists of water” appear regularly in encyclopedias Furthermore, 80% of the cytoplasm (basic cell material) of a standard animal cell is described as water in biology textbooks. The analysis of cytoplasm and its appearance in textbooks took place hundreds of years after the revelation of the Qur’an. It is therefore impossible for this fact, now accepted by the scientific community, to have been known at the time the Qur’an was revealed. Yet, attention was drawn to it in the Qur’an 1,400 years before its discovery.
