Other names for it are the dome of the Bekh Bekh, the chapel of Al Khader, Mosque of the Prophet. It was named after the Sufi Sheikh Mohammed Al-Khalili, who used to lead the prayers as an Imam, and worship Allah. It’s located in the Rock’s nave, northwest of the Dome of the Rock, in the middle of Al-Aqsa Mosque. It was built by the Ottoman governor of Jerusalem Mohammed Beck. It was established in the Ottoman era in (1112 AH / 1700 AD). It’s a square building on four Staff, topped by a shallow dome with Ottoman style, its four facades have eight rectangular windows in each two windows interface. In the eastern facade of the building a small door topped with inscription bearing the name and date of the building. Inside the dome is a mihrab decorated with mosaics from a royal calcareous stone with a shallow stone garden, and beneath the building of the dome of the Khalili there is a building below, called a cave of spirits, reached through a stone staircase cut from the rock, this light-filled ventilated cavern is not used. Today is the Office of the Committee for the reconstruction of Al Aqsa Mosque. Also, the corner of Muhammadiyah, the inscription is a combination of several poetic verses above an entrance Dome One of the verses indicates the date of the dome's construction according to the Sentences:
Muhammad has his date" "We said, enter it safely."
The Ottoman era was known for its history using words and poetry.
Those wo know how to do some calculations will find that the sentences (Abjad Hughes) where the alphabet is equal to aleph equals 1, and Ba 2 and Kaf 20. The sum of the points of the sentence & quote then the sum of the sentence numbers is "date, and we said, enter it safely" (equals 1112 Hijri / 1700 AD).
Note: It seems that Muhammad Beck ordered a well to be dug in the rock and then built his dome above it. we can see the effects of the well, then after abandoning the well for too long, it dried, and a mihrab replaced it inside the room and served as a basement for the Sufis. With the abandonment of Al Khader Corner and using it as a store, it was renamed as the "Bekh Bekh”.The dome is used today as the office of the Committee of Al-Aqsa Mosque Renovation.
