The Kitáb-i-Aqdas - The Most Holy Book
The ancient Arabic system of allocating a numerical value to letters of the alphabet, so that numbers may be represented by letters and vice versa. Thus every word has both a literal meaning and a numerical value.
Báb, The
Literally the "Gate", the title assumed by Mí­rzá ‘Alí­-Muhammad (1819-1850) after the Declaration of His Mission in Shí­ráz in May 1844. He was the Founder of the Bábí­ Faith and the Herald of Bahá’u’lláh.
Bahá means Glory. It is the Greatest Name of God and a title by which Bahá’u’lláh is designated. Also, the name of the first month of the Bahá’í­ year and of the first day of each Bahá’í­ month.
The "Glory of God", title of Mí­rzá Husayn-‘Alí­ (1817-1892), the Founder of the Bahá’í­ Faith.
The Bayán ("Exposition") is the title given by the Báb to His Book of Laws, and it is also applied to the entire body of His Writings. The Persian Bayán is the major doctrinal work and principal repository of the laws ordained by the Báb. The Arabic Bayán is parallel in content but smaller and less weighty. References in the annotations to subjects found in both the Persian Bayán and the Arabic Bayán are identified by use of the term "Bayán" without further qualification.
The "Right of God". Instituted in the Kitáb-i-Aqdas, it is an offering made by the Bahá’í­s through the Head of the Faith for the purposes specified in the Bahá’í­ Writings.
Literally "the Dawning-place of the praise of God", the designation of the Bahá’í­ House of Worship and its dependencies.
A unit of weight, equivalent to a little over 3 1/2 grammes, used in the Kitáb-i-Aqdas with reference to quantities of gold or silver for various purposes, usually in amounts of 9, 19 or 95 mithqáls. The equivalents of these in the metric system and in troy ounces (which are used in the measurement of precious metals), are as follows:

9 mithqáls = 32.775 grammes = 1.05374 troy ounces
19 mithqáls = 69.192 grammes = 2.22456 troy ounces
95 mithqáls = 345.958 grammes = 11.12282 troy ounces

This computation is based on the guidance of Shoghi Effendi, conveyed in a letter written on his behalf, which states "one mithqál consists of nineteen nakhuds. The weight of twenty-four nakhuds equals four and three-fifths grammes. Calculations may be made on this basis." The mithqál traditionally used in the Middle East had consisted of 24 nakhuds but in the Bayán this was changed to 19 nakhuds and Bahá’u’lláh confirmed this as the size of the mithqál referred to in the Bahá’í­ laws (Q&A 23).
A unit of weight. See "mithqál".
The Báb’s commentary on the Súrih of Joseph in the Qur’án. Revealed in 1844, this work is characterized by Bahá’u’lláh as "the first, the greatest, and mightiest of all books" in the Bábí­ Dispensation.
Shoghi Effendi
Shoghi Effendi (1897-1957), Guardian of the Bahá’í­ Faith from 1921-1957. He was the eldest grandson of ‘Abdu’l-Bahá and was appointed by Him as the Head of the Faith.
Literally "the Black Pit". The dark, foul-smelling, subterranean dungeon in Tihrán where Bahá’u’lláh was imprisoned for four months in 1852.
The "Servant of Bahá", 'Abbas Effendi (1844-1921), the eldest son and appointed Successor of Bahá’u’lláh, and the Centre of His Covenant.
