Rub ElHibz Adjustable Open Ring

Rub El Hizb is an Islamic symbol (۞) composed of two overlapping squares, resembling an eight-pointed star. In Arabic, the term Rub El Hizb means something divided into quarters, which can be seen in the symbol's image where the edges of the two squares are separated.
Rub El Hizb was used by past Muslims for reciting and memorizing the Quran. The symbol represents each quarter of a Hibz, which is a section in the Holy Quran. This symbol also marks the end of a chapter in Arabic calligraphy.
Although Islam prohibits the use of images and symbols, believers can use geometric shapes and designs such as Rub El Hizb to convey religious concepts and beliefs.
The design of Rub El Hizb is basic, consisting of two superimposed squares with a circle in the center. These basic geometric shapes create a more complex eight-pointed star with eight equal triangular sections.
The symbol is used as a way to assist in Quran recitation, which is an important part of Islamic life. It is used to divide verses into quantifiable passages, allowing readers or reciters to track Hibzs. This is why the symbol's name comes from the word Rub, meaning quarter or fourth, and Hizb, meaning a group, together meaning grouping into quarters.
In the Quran, a 'Hizb' corresponds to half of a Juz, which divides the Quran into 30 parts. The Quran contains a total of 60 Hizbs. Therefore, Rub El Hizb indicates a quarter of a Hizb or an eighth of a Juz. This symbol is used in Quranic text as a marker indicating the end of a verse. It provides readers with a convenient way to find and remember their reading progress.
