Bahá’í Prayers: A Selection of Prayers Revealed by Bahá’u’lláh, the Báb, and ‘Abdu’l-Bahá

“The daily obligatory prayers are three in number. … The believer is entirely free to choose any one of these three prayers, but is under the obligation of reciting one of them, and in accordance with any specific directions with which they may be accompanied.”

“By ‘morning,’ ‘noon’ and ‘evening,’ mentioned in connection with the Obligatory Prayers, is meant respectively the intervals between sunrise and noon, between noon and sunset, and from sunset till two hours after sunset.”—Synopsis and Codification of the Kitáb-i-Aqdas, p. 36 4
