Egyptian nationalism was territorial, not Arab, before the world wars

Evidence

The Egyptian nationalist movement in the 19th and in the early 20th centuries was concentrated wholly on Egyptian national and patriotic aspirations, conceived in terms of Egypt as a territorial nation. Insofar as Egypt was seen as part of a larger entity, this was Islamic, and indeed Ottoman, in that loyal Egyptian Muslims under British occupation felt that their rightful suzerain was the Ottoman Sultan. — Bernard Lewis, From Babel to Dragomans, 893
