In Islamic belief God has 99 names, and in some Islamic traditions it is believed that there is a special hidden 100th name, which is the greatest. In Baháʼí belief the "Greatest Name" is "Baháʼ" (), translated as "glory" or "splendour". Many symbols of the Baháʼí Faith derive their significance from the word Baháʼ, and it is the root word used in many other names and phrases including Baháʼí (a follower of Baháʼ), Baháʼu'lláh (Glory of God), ʻAbdu'l-Bahá (Servant of Glory), Yá Baháʼu'l-Abhá (O Thou Glory of the Most Glorious), and Alláh-u-Abhá (God is Most Glorious).
