It is in the city of [[Medina]] in [[Saudi Arabia]]. Al-Masjid an-Nabawi was the third mosque built in the [[history of Islam]] and is now one of the largest mosques in the world. It is the second-holiest site in [[Islam]], after [[Masjid al-Haram]] in [[Mecca]]. The site was originally adjacent to Muhammad's house; he settled there after his [[Hijra (Islam)|Hijra]] (emigration) to Medina in 622 CE. He shared in the heavy work of building. The original mosque was an open-air building. The mosque served as a community center, a court, and a religious school. There was a raised platform for the people who taught the [[Quran]]. Subsequent Islamic rulers greatly expanded and decorated it. In 1909, it became the first place in the [[Arabian Peninsula]] to be provided with [[Electric light|electrical lights]].<ref>{{Cite web |title=The History of Electrical lights in the Arabian Peninsula |url=http://www.suhuf.net.sa/2001jaz/jul/3/ec19.htm |access-date=2016-11-22 |archive-date=2015-10-01 |archive-url=https://web.archive.org/web/20151001160159/http://www.suhuf.net.sa/2001jaz/jul/3/ec19.htm |url-status=dead }}</ref> The mosque is under the control of the [[Custodian of the Two Holy Mosques]].
