Abjad

The Abjad numeral system assigns numerical values to the 28 letters of the Arabic alphabet in the original Semitic letter order rather than the modern Arabic sequence. Used historically for chronograms in Islamic scholarship and for mystical purposes within Sufi traditions, Abjad shares structural features with Hebrew Gematria and Greek Isopsephy. NUMINOS includes Abjad calculation alongside other Gematria systems.
