Why Dhu al-Qarnayn’s Dam is Impenetrable? A Chemical and Physical Study

: By development of human scientific abilities, more miracle aspects and wonders of the Qur’an have been recognized� Stating the story of Dhu al-Qarnayn and constructing of dam, verses (Q�18:83-98) have pointed some valuable scientific aspects regarding chemistry, physics and metallurgy� The instruction for the structure reveals the non-accidental process, because the precise expected physical, chemical and metallurgical properties� The three-layer structures of dam with dendrite like microstructure in its matrix will guarantee the durable structure against most chemical destructive agent, mechanical damage and thermal threats� Hence the powerful people of Gog and Magog could not overcome the high tensile strength of iron, high ductility of copper and the high toughness of Cu-Fe alloy� The high thermal and temperature resistance are the evidence for more structural power� Such masterpiece of engineering, in technology of alloying, could not be based on the knowledge of common craftsmen of that time, but it must have been based on superhuman wisdom� Consequently, although the Qur’an is a book of guidance, but it reports some original scientific issues, such as the Dhu al-Qarnayn story� These were not known in the age of revelation and after progressing in science, but the truth of considered issues has been proved� However, because of the clear instruction, and the precise prediction of properties, it is possible to use the verses as an excellent idea for scientific advancement, rather than reporting events�
