Index term: Jerusalem
n7.
When ye desire to perform this prayer, turn ye towards the Court of My Most Holy Presence, this Hallowed Spot that God hath . . . decreed to be the Point of Adoration for the denizens of the Cities of Eternity
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.

O Emperor of Austria! He Who is the Dayspring of God’s Light dwelt in the prison of 'Akká at the time when thou didst set forth to visit the Aqsá Mosque.
Francis Joseph (Franz Josef, 1830-1916), Emperor of Austria and King of Hungary, made a pilgrimage to Jerusalem in 1869. While in the Holy Land he failed to take the opportunity to inquire about Bahá’u’lláh Who at that time was a prisoner in 'Akká (Acre).
The Aqsá Mosque, literally, the "Most Distant" Mosque, is referred to in the Qur’án, and has become identified with the Temple Mount in Jerusalem.
