Fu Ad فؤاد

Fu Ad (فؤاد) — Distinguish from qalb. In classical Sufi anthropology (Tirmidhi, Kalābādhī, Hujwīrī) the fu’ād is the innermost stratum — deeper than qalb, the seat of perceptive certainty (ʿayn al-yaqīn). In Akbarian usage the distinction is preserved but the terms are sometimes used interchangeably in poetry. When both appear in a single passage (as in Tarjumān Ode I, lines 1 and 2), the apparatus should preserve the distinction even if the line-level English rendering domesticates both to “heart.” Range card mandatory when both terms co-occur.
