al-Masjid an-Nabawī (Arabic: المسجد النبوي‎), also called the Prophet's Mosque, is a historic mosque originally established and built by prophet Muhammad, situated in the city of Medina. al-Masjid an-Nabawi was the second mosque built, first being the Quba Mosque, in the history of Islam and is now one of the largest mosques in the world. The current plan of the mosque dates back to the early years of 1990s and incorporates the constructions from late Ottoman era to early and modern Saudi periods. Today the Mosque of the Prophet is an extensive complex of buildings and structures that not only covers nearly all of the Medina of the early seventh century CE; it also incorporates several other sites like Jannatul Baqi and Saqifah Bani Saidah that were located clearly outside of the city bounds.Overview

It is always open, regardless of date or time. The site was originally adjacent to Muhammad's house; the original mosque was an open-air building and served as a community center, a court, and a school as well.

The mosque is under the control of the Custodian of the Two Holy Mosques. The mosque is located in what was traditionally the center of Medina, with many hotels and old markets nearby. It is a major pilgrimage site. Many pilgrims who perform the Hajj go on to Medina to visit the mosque, due to its connection to Muhammad. The mosque has been extended over the years, the latest being in the mid 1990s. One of the most notable features of the site is the green dome over the centre of the mosque, where the tomb of Prophet Muhammad and early Islamic leaders Abu Bakr and Umar are located.

In order to finance the scholarly and educational activities in the Masjid al-Nabawi as well as the renovation and reconstruction projects, several foundations were started to be established in the Umayyad era, and they have been increasing in number since Brief History of Masjid Nabawi

The mosque was originally built by the prophet Muhammad in 622 CE after his arrival in Medina (called Yathrib at the time) has a long and storied history of nearly fifteen hundred years. The land for the mosque was purchased from two orphans, Sahl and Suhayl. The price of the buying was paid for by Abu Ayyub al-Ansari, and it took seven months to complete the construction of the mosque. At the time the Prophet's Mosque was not only used as a prayer house, rather as a community, social services and administrative center, court house and a town hall. Various kings, sultans, ameers and other notable people have contributed towards its construction and expansions which has led to the current development and architecture of current building.then.
