Al-Azhar's waqf endowments were nationalized into Egypt's Ministry of Awqaf in 1952; the Ministry administers the national waqf estate as a whole and no source found in this pass isolates Al-Azhar's own share of it, so no current valuation of Al-Azhar's institutional wealth can be attested.
What would resolve this A Ministry of Awqaf or Egyptian government disclosure, or an independent scholarly study of Egypt's waqf sector, that breaks out Al-Azhar's own endowment holdings from the national total.
