We have enjoined obligatory prayer upon you, with nine rak'ahs, to be offered at noon and in the morning and the evening unto God, the Revealer of Verses. We have relieved you of a greater number, as a command in the Book of God. He, verily, is the Ordainer, the Omnipotent, the Unrestrained. 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.

The "Point of Adoration", that is, the point to which the worshipper should turn when offering obligatory prayer, is called the Qiblih. The concept of Qiblih has existed in previous religions. Jerusalem in the past had been fixed for this purpose. Muhammad changed the Qiblih to Mecca. The Báb's instructions in the Arabic Bayán were:

The Qiblih is indeed He Whom God will make manifest; whenever He moveth, it moveth, until He shall come to rest.

This passage is quoted by Bahá'u'lláh in the Kitáb-i-Aqdas (137) and confirmed by Him in the above-noted verse. He has also indicated that facing in the direction of the Qiblih is a "fixed requirement for the recitation of obligatory prayer" (Q&A 14 and 67). However, for other prayers and devotions the individual may face in any direction.
