Usul wa Shawahid al-Nazar al-Aqli fi al-Quran wa al-Fikr al-Islami

Usul wa Shawahid al-Nazar al-Aqli fi al-Quran wa al-Fikr al-Islami (Principles and Evidences of Rational Inquiry in the Quran and Islamic Thought) is a philosophical treatise by Abd al-Qadir Mahmud examining the Quranic foundation for rational reflection and how Muslim theologians, philosophers, and mystics derived proofs of the divine from scripture Usul wa Shawahid al-Nazar…+1.

Background and Purpose

The work originated from notes the author compiled during his higher academic studies, drawing upon lectures in Islamic philosophy delivered forty years earlier by Muhammad Abd al-Hadi Abu Ridah, a disciple of Mustafa Abd al-Raziq Usul wa Shawahid al-Nazar…. The text addresses the relationship between revelation and philosophical reasoning, positing that religious devotion preceded philosophical speculation in human history Usul wa Shawahid al-Nazar…. Mahmud argues that the Quran established a decisive turn by rooting religious faith in empirical observation, rational discernment (al-nazar al-aqli), and verifiable proof, rather than uncritical imitation (taqlid) or purely abstract dialectical categories Usul wa Shawahid al-Nazar…+1.

Method and Key Arguments

Mahmud outlines the Quranic approach to theology, emphasizing that scripture directs human intellect toward the observable order of the natural world and the human constitution as the starting point for knowing God Usul wa Shawahid al-Nazar…. The book highlights several core themes:

• The Inaccessibility of the Divine Essence: The Quran directs reflection toward God’s acts and attributes rather than His quiddity (mahiyyah) or inner essence (dhat), because the finite human mind cannot encompass the infinite, and the divine is uniquely beyond logical classification by proximate genus and specific difference Usul wa Shawahid al-Nazar…+1.
• Innate Knowledge versus Discursive Proof: The author analyzes the interplay between primordial intuition (fitrah)—linked to the primordial covenant mentioned in the Quran—and rational deduction. While theologians and philosophers emphasize discursive proofs (al-istidlal), Sufis emphasize spiritual purification (al-tasfiyah al-ruhiyyah) to uncover innate knowledge; Mahmud maintains that both avenues are complementary and mutually reinforcing Usul wa Shawahid al-Nazar…+1.
• Harmony of Reason and Science: Citing thinkers such as Al-Kindi and Ibn Rushd, the work stresses that demonstrative truth cannot contradict revealed truth, concluding with a call for contemporary scientific achievements to be guided by ethical and theological responsibility Usul wa Shawahid al-Nazar…+1.

Survey of Theological and Philosophical Proofs

The treatise systematically categorizes how major figures in Islamic thought derived rational demonstrations of God's existence from Quranic verses:

• Ibn Rushd: Formulated two primary Quranic proofs: the argument from invention (dalil al-ikhtira'), based on the origination of life and celestial bodies, and the argument from providence (dalil al-'inayah), grounded in the cosmic order's suitability for human life Usul wa Shawahid al-Nazar…+1.
• Abu al-Hasan al-Ash'ari: Utilized the observed stages of human physical development, arguing that human inability to create faculties or prevent mortality rationally proves the necessity of a non-corporeal Creator Usul wa Shawahid al-Nazar…+1.
• Ibrahim al-Nazzam: Proposed the argument from the coexistence of contrary elements, asserting that opposing forces joined against their inherent nature indicate a compelling, external Creator Usul wa Shawahid al-Nazar….
• Al-Mutahhar ibn Tahir al-Maqdisi: Summarized several arguments, including the argument from existential need and desperation (dalil al-iftiqar or al-idtarar), the consensus of nations, the teleological proof from cosmic order, and the gradation of creatures Usul wa Shawahid al-Nazar…+1.
• Al-Kindi and Al-Farabi: Al-Kindi's proofs included the finitude of the universe in time, space, and motion (dalil al-tanahi), change (dalil al-taghayyur), and teleology, while al-Farabi formulated the argument from contingency (dalil al-imkan), distinguishing between possible and necessary existence Usul wa Shawahid al-Nazar….
