According to search-discovered classical Islamic scholarship, water (al-Ma') is a foundational element in the Quran, presented not merely as a physical substance but as a profound symbol of divine power and mercy. Ibn Kathir's tafsir on Quran 21:30, "And We made from water every living thing," establishes water as the divine origin of all life. This understanding is reinforced across dozens of verses where water acts as a multifaceted sign (Ayah): it is the purifying agent for worship (Taharah), the vehicle of Allah's sustenance through rain (Rizq), a depiction of reward in Paradise's flowing rivers, and an instrument of divine justice. Prophetic traditions, such as the prohibition against wastefulness even by a flowing river, elevate water conservation to a spiritual discipline. This synthesis establishes water as a sacred trust, obligating Muslims to practice stewardship (Khilafah) over this life-giving resource.
