Rub el Hizb

The Rub el Hizb (Arabic: ربع الحزب‎‎ rubʿ al-ḥizb) is a Muslim symbol, represented as two overlapping squares, which is found on a number of emblems and flags. In Arabic, Rubʻ means "one fourth, quarter", while Hizb means a group or party. Initially, it was used in the Quran, which is divided into 60 Hizb (60 groups of roughly equal length); the symbol determines every quarter of Hizb, while the Hizb is one half of a juz'. The main purpose of this dividing system is to facilitate recitation of the Qur'an.

The symbol is used as a marker for the end of a chapter in Arabic calligraphy. It is represented by two overlapping squares as in the Unicode glyph ۞ at U+06DE.
