The interaction and mutual influence between the concepts of economy and culture form a tangled and often confusing relationship that leads to conceptual overlap. The present study seeks to establish a principled equilibrium and a sound mode of interaction between cultural and economic systems by drawing on the Qur’an. Cognitive and perceptual sciences shape how societies understand issues, since the primary cause of perceptual and computational error lies in assigning improper weight to these concepts and in constructing unbalanced relations between them.Using a qualitative content analysis approach, this article examines the cultural–economic constellation within human life and social developments. Cognitive clarity and cognitive disorders-derived from Sūrat al-Nūr and formulated as sarābī disorder (mirage-like misperception) and lughajī disorder (obstinate distortion)-are analyzed alongside cultural–economic interactions based on Sūrat al-Zukhruf, with emphasis on foundational enabling structures such as qawm, qaryah, ābāʾ, and banāt. The findings propose a model of proper cultural-economic interaction in which perceptual disorders-whether sarābī or lughajī-disrupt the balance between cultural and economic variables and produce cognitively flawed decision-making. In response, the concepts of “water-weight” (thaqal ābī) and “light-weight” (thaqal nūrī) are introduced as fundamental principles for restoring cognitive transparency and recalibrating the correct relational pattern between culture and economy.
