Said left Cairo for Saudi Arabia, where he lived almost a year, during which the United Arab Republic by the union between Syria and Egypt came into existence. Said then returned to Syria (known then as the Northern Region of the United Arab Republic) to complete military service; while he was in the army, the separation of the union took place. While everyone complied with the orders given by commanders in the military, he clearly opposed to participate in any military actions against the "Union", leading officials to put him under military internal detention, and did not leave until after the end of the matter.
