Masjid al-Qiblatayn or Mosque of the Two Qiblas

The Masjid al-Qiblatayn translated as 'Mosque of the Two Qiblas' is a mosque in Medina believed by Muslims to be the place where the final Islamic prophet, Muhammad, received the command to change the Qibla (direction of prayer) from Jerusalem to Mecca. The mosque was built by Sawad ibn Ghanam ibn Ka'ab during the year 2 AH and is one of the few mosques in the world to have contained two mihrabs (niches indicating the qibla) in different directions. The mosque is located on the north-west of the city of Medina, on Khalid ibn al-Walid Road. The mosque was initially maintained by Caliph Umar ibn al-Khattāb. The last pre-modern renovation was by Suleiman the Magnificent who reconstructed the mosque.

The mosque is among the earliest mosques in Medina and was built by Sawad ibn Ghanam ibn Ka'ab al-Ansari in the Islamic year 2 AH,[1] and the name of the mosque goes back to the lifetime of Muhammad, when his companions named it after an event that took place on the 15th of Sha'baan the same year, when Muhammad received revelation from Allah instructing him to take the Kaaba as the qibla during the Dhuhr prayer, instead of Baytul Maqdis, which was the Masjid Al Aqsa in Jerusalem.[9] He later announced this to his companions in his own mosque, after which the news began to spread. Many pilgrims who go to Mecca for Hajj often visit Medina, where some visit this mosque because of its historical significance.

The main prayer hall adopts rigid orthogonal geometry and symmetry which is accentuated by the use of twin minarets and twin domes. Living accommodations for the Imam, the Muezzin and the caretaker are discretely grouped in one block to the west of the main structure. The prayer hall consists of a series of arches which support barrel-vaults running parallel to the qibla wall. These vaults are interrupted by two domes which establish an axis in the direction of Mecca.

The main dome to the south is raised on a drum of clerestory windows which allow light to filter into the interior directly above the mihrab. The second, false dome is linked to the first by a small cross-vault to symbolise the transition from one qibla to another. Below it, a replica of the mihrab found in the lower chamber of the Dome of the Rock in Jerusalem reminds onlookers of the oldest extant mihrab of Islam.
