Conversion of non-Islamic places of worship into mosques
The conversion of non-Islamic places of worship into mosques occurred during the life of Muhammad and continued during subsequent Islamic conquests and invasions and under historical Muslim rule. Hindu temples, Jain temples, churches, synagogues, and Zoroastrian fire temples have been converted into mosques.
Several such mosques in the areas of former Muslim rule have since been reconverted or have become museums, including the Parthenon in Greece and numerous mosques in Spain, such as Mosque–Cathedral of Córdoba. Conversion of non-Islamic buildings into mosques influenced distinctive regional styles of Islamic architecture.
Qur'anic holy sites
Jerusalem
Upon the capture of Jerusalem, it is commonly reported that Umar refused to pray in the Church of the Holy Sepulchre in spite of a treaty. The architecturally similar Dome of the Rock was built on the Temple Mount, which was a destroyed site of the holiest Jewish temple, destroyed by the Romans in AD 70 and with consistent Jewish presence in Jerusalem has always been a site of religious prayer for Jews. Umar initially built there a small prayer house which laid the foundation for the later construction of the Al-Aqsa Mosque by the Umayyads.Conversion of church buildings

Turkey
Istanbul
Hagia Sophia
Following the Ottoman conquest of Anatolia, virtually all of the churches of Istanbul were converted into mosques except the Church of Saint Mary of the Mongols.- Hagia Sophia was the cathedral of Constantinople in the state church of the Roman Empire and the seat of the Eastern Orthodox Church's Patriarchate. After 1453 it became a mosque, and since 1931 it has been a museum in Istanbul, Turkey. From the date of its dedication in 360 until 1453, it served as the Orthodox cathedral of the imperial capital, except between 1204 and 1261, when it became the Roman Catholic cathedral under the Latin Patriarch of Constantinople of the Western Crusader-established Latin Empire. In 1453, Constantinople was conquered by the Ottoman Turks under Sultan Mehmed II, who subsequently ordered the building converted into a mosque. The bells, altar, iconostasis, ambo and sacrificial vessels were removed and many of the mosaics were plastered over. Islamic features – such as the mihrab, minbar, and four minarets – were added while in the possession of the Ottomans. The building was a mosque from 29 May 1453 until 1931, when it was secularised. It was opened as a museum on 1 February 1935. On 10 July 2020, the decision of the Council of Ministers to transform it into a museum was canceled by Council of State and the Turkish President Erdoğan signed a decree annulling the Hagia Sophia's museum status, reverting it to a mosque.

- The Ashkenazi synagogue on Wagenstraat street of The Hague, built in 1844, became the Aqsa Mosque in 1981. The synagogue had been sold to the city by the Jewish community in 1976, on the grounds that it would not be converted into a church. In 1979 Turkish Muslim residents occupied the abandoned building and demanded it be turned into a mosque, citing alleged construction safety concerns with their usual mosque. The synagogue was conceded to the Muslim community three years later.
