'Abdu'l-Bahá defined the essential architectural character of the Bahá'í House of Worship as consisting of a nine-sided, circular building. All Houses of Worship, therefore, incorporate these design features and the Master's instructions guide the architects in the preparation of their unique, individual designs. The design of the first 'Ishqábád Temple, prepared by Ustád 'Ali-Akbar-i-Banná, was likewise influenced and inspired by 'Abdu'l-Bahá's archetypal design. Shoghi Effendi, in "God Passes By", p. 300, refers to the Master's intense personal interest in the construction of the 'Ishqábád House of Worship. He affirms that it was "fostered by Him at every stage in its development".
