Rub el Hizb
The Rub el Hizb (Arabic: رُبْعُ الْحِزْبِ or رُبُعُ الْحِزْبِ, romanized: rubʿ al-ḥizb, lit. 'quarter of the party') is an Islamic symbol in the shape of an octagram, represented as two overlapping squares ۞. While its main utility today is to mark a division inside some copies of the Quran to facilitate recitation, it has originally featured on a number of emblems and flags in the past and continues to do so today.
