According to the official report, Hassanein competed in both the individual foil and épée events. In the former he was part of Pool XIV, which included upcoming bronze medalist Richard Verderber of Austria, and it is recorded only that he did not advance to the quarterfinals. In the latter he was placed in Pool II, which included eventual Olympic champion Paul Anspach of Belgium, and again it is noted only that he did not make it out of the round. Hassanein would go on to compete in both disciplines at the 1920 Summer Olympics, and in épée in 1924, but never won a medal.
