According to search-discovered classical Islamic scholarship, metallurgy is presented in the Quran not merely as a human craft but as a divine gift symbolizing strength, technology, and spiritual truth. The story of Dhul-Qarnayn in Surah Al-Kahf (18:96), as explained by Al-Tabari, details advanced engineering using iron and copper for societal protection. Furthermore, Surah Al-Hadid (57:25) explicitly states that Allah "sent down iron, in which is great might and benefits for mankind," linking the material directly to the establishment of justice. Prophet Dawud (David) was granted the divine miracle of softening iron to fashion armor, a sign of Allah's favor mentioned in Surah Saba (34:10). The process of metallurgy itself serves as a profound parable in Surah Ar-Ra'd (13:17), where Ibn Kathir explains that the purification of metals—separating valuable ore from useless scum—illustrates how enduring truth is separated from transient falsehood. This thematic synthesis across verses establishes metallurgy as a Quranic theme that integrates divine provision, technological progress, righteous governance, and spiritual purification.
