reason / intellect / understanding
Masculine noun (maṣdar). Verb: عَقَلَ (to reason/understand). The Quran never uses ʿaql as a noun directly - always as a verb (تَعْقِلُونَ, يَعْقِلُونَ), emphasizing active reasoning.
The Quran addresses the ʿaql over 49 times, always in verb form - reason is an activity, not a passive possession. Anti-intellectualism contradicts the Quran.
