Both Hakim Sanai and Jalal al-Din Rumi utilize the metaphor of the 'squint-eyed' (ahwal) person to illustrate spiritual delusion and the inability to perceive divine unity (tawhid). Sanai introduces this in the Hadiqat al-Haqiqah through a son who mistakenly sees multiplicity (two instead of one), while Rumi later adapts this imagery in the Masnavi—such as the parable of the double-sighted stranger in Kash—to demonstrate how impaired spiritual vision creates an illusion of duality. Comparing these allegories highlights Sanai's profound influence on Rumi's didactic poetry and the shared Sufi symbol of diplopia as a failure to grasp the singular reality of God.
