To say a special prayer, known as Obligatory Prayer, everyday

We have enjoined obligatory prayer upon you, ... to be offered at noon and in the morning and the evening unto God, the Revealer of Verses ... When ye desire to perform this prayer, turn ye towards the Court of My Most Holy Presence, this Hallowed Spot that God hath made the Centre round which circle the Concourse on High, and which He hath decreed to be the Point of Adoration for the denizens of the Cities of Eternity, and the Source of Command unto all that are in heaven and on earth; and when the Sun of Truth and Utterance shall set, turn your faces towards the Spot that We have ordained for you. He, verily, is Almighty and Omniscient. (Baha'u'llah, The Kitab-i-Aqdas, p. 21)
