1 Reinterpreting the Quranic Concepts of "Shajar" and "Shajara" for Modern Applications in Science and Technology By Nabeel Alkhalidy 1 Abstract: This paper embarks on an interdisciplinary journey to re-examine the Qur'anic concepts of Shajara (a singular branching structure) and Shajar (interconnected branching networks). Moving beyond traditional botanical interpretations, it will be argued that these terms encapsulate the essence of optimal branching theory and fractal geometry, principles governing the efficient transport and distribution of resources throughout the natural world (West, 1997). This research presents a thematic ta‘wīl (thematic exploration) that seeks not to replace classical meanings but to add complementary layers of interpretive depth, revealing the Qur'an's profound relevance to contemporary scientific and technological challenges By understanding Shajarah as the fundamental, self-similar branching pattern observed in phenomena from plant roots and vascular systems to lightning strikes and river deltas, and Shajar as the overarching network formed by these structures, we uncover a timeless blueprint for optimised design. This study argues that the Qur'an, through these seemingly simple yet deeply insightful concepts, foreshadows modern scientific understanding of efficiency in natural systems This reinterpretation offers a powerful framework for developing innovative and sustainable solutions across critical domains. It has direct, actionable applications in designing urban road networks that optimise traffic flow, creating biomimetic architectural layouts for superior energy efficiency, and crafting data and logistics networks that leverage fractal patterns for enhanced connectivity and reduced energy consumption. Furthermore, we explore how these principles can revolutionise energy distribution systems, leading to more robust and efficient grids (Bejan, A., & Lorente, S., 2010). This paper seeks to inspire researchers, engineers, and policymakers to embrace an integrated perspective, cultivating a deeper recognition of how divine wisdom can inform innovative technological and environmental solutions for our time 1 Quran Researcher at IQRA (www.iqra.study) and The Sibaway Institute ( www.sibawayinstitute.com)
