This is a view under the Qblyu Mosque in the Masjid al-Aqsa platform. Some believe that the stone pillars were built by the jins in the time of the Prophet Suleiman (peace be upon him).
Allah said in only Quran Surah Saba:
And to Solomon (We subjected) the wind, its morning (stride from sunrise till midnoon) was a month’s (journey), and its afternoon (stride from the midday decline of the sun to sunset) was a month’s (journey i.e. in one day he could travel two months’ journey). And We caused a fount of (molten) brass to flow for him, and there were jinns that worked in front of him, by the Leave of his Lord, and whosoever of them turned aside from Our Command, We shall cause him to taste of the torment of the blazing Fire.
They worked for him what he desired, (making) high rooms, images, basins as large as reservoirs, and (cooking) cauldrons fixed (in their places). “Work you, O family of Dâwud (David), with thanks!” But few of My slaves are grateful. [34: 12-13]
There is an adjacent room with a lattice (above) through which you can see the floor below, where the oil for heating the mosque was burned.
Maymunah bint Sa’ad (may Allah be pleased with him) says that she asked the Prophet (saw): “O Prophet (saw)! Tell us about Bayt al-Maqdis. ” He said, “Visit it for prayer.” She further asked: “If one of us cannot visit it, what should we do?” He (saw) said: “If you cannot go to prayer there, then send some oil to use in its lamps; who gives oil for it’s lamps, will be as if he were praying in it. ” [Imam Ahmad, Ibn Majah, Sunan Abu Daud and al-Tabarani]
Jewish tradition says that on the place where Masjid al-Aqsa was built, the Jerusalem temple was originally located. The destruction of the First Temple, known as the Temple of Solomon, is attributed to the Babylonians in 587 BC. E., And there are no physical remains indicating its presence or structure. The construction of the Second Temple began during the reign of the Persian king Cyrus the Great, but this temple was destroyed by the Roman emperor (then general) Titus in 70 CE. All that remains of it is the Western Wall, which is considered the remnant of the platform of this second temple.
The basement also houses a library containing about 130,000 books. There are also about 4,000 manuscripts that were donated from private collections of Jerusalem families. UNESCO states that the library contains “one of the most important collections of Islamic manuscripts in the world.”
