What the source says
Referenced, awaiting primary-source reviewOn 17 November 1915, Sultan Yusef signed a dahir introducing the current flag design. Red represents the blood of the ancestors and unity [and has] association with the Alawi dynasty. The green star represents the five pillars of Islam. [Sultan Yusef:] our noble vision decided to distinct our joyful flag by making the five-pointed seal of Solomon in the middle in green [to distinguish it] from the rest of the kingdoms.
