In Middle Ages, the eight-point star was widely used as a symbol in Islamic Art. This symbol is called “Khatim” or “Khatim Sulayman”, a.k.a the seal of prophets, as in the signet ring. Some Zellige artisans usually refer to the eight-point star as “Sibniyyah”, “Sabniyyah”, which is a derivative of the number seven “Sab’ah”.
