| In Islam there is a tradition that among the various names of God,
one is the greatest. However, the identity of this Greatest Name is hidden. Bahá'ís believe that the Greatest Name of God is Bahá, which means glory,
splendor or light. Bahá,
or any of its derivatives such as Abhá,
as well as certain phrases such as Alláh'u'Abhá, Yá Bahá'u'lláh,
or Yá Bahá'u'l-Abhá, are all referred to as the Greatest Name.
Yá Bahá'u'l-Abhá is an invocation which can be translated either
as 'O Glory of Glories' or 'O Glory of the All-Glorious'. This invocation calligraphically
designed by Mishkín-Qalam is used by Bahá'ís in their homes as a dignified wall-hanging. The ringstone
symbol is another representation of the Greatest Name.
