Masjid al-Nabawi was built by Hz. Peygamber Muhammad in 622 CE upon his arrival in Medine. Originally a simple structure of palm trunks and mud bricks measuring 30x35 meters, it has been expanded by the caliphs, Umayyads, Abbasids, Ottomans, and Saudis to its current capacity of over one million worshippers.
When Hz. Peygamber Muhammad (sallallahu aleyhi ve sellem) arrived in Medine during the Hijrah in 622 CE, one of his first acts was to build a cami. He purchased a plot of land where his camel had stopped (an area previously used as a date-drying yard) and personally participated in the construction alongside his companions. The original cami was a simple open-air structure measuring approximately 30 by 35 meters, with walls of sun-dried mud bricks, a roof of palm fronds and mud over palm trunk columns, and a qibla wall (initially facing Jerusalem, later changed to face Mekke). Hz. Peygamber's apartments, shared with his wives, were built along the eastern wall. This humble structure served as the center of the Muslim community — a cami, a school, a court, a parliament, and a social welfare center.
The cami was expanded during Hz. Peygamber's lifetime as the Muslim community grew. After his death, Abu Bakr maintained the cami as it was. Umar ibn al-Khattab expanded it in 638 CE, and Uthman ibn Affan further enlarged it in 650 CE, introducing carved stone columns and a teak ceiling. The Umayyad Caliph al-Walid ibn Abdul Malik (r. 705-715 CE) undertook the most significant early expansion, incorporating Hz. Peygamber's burial chamber within the cami structure, introducing marble columns, gold mosaics, and minarets, and roughly doubling the cami's area. This expansion set the architectural template for centuries.
The Ottomans invested heavily in Hz. Peygamber's Mosque over four centuries, adding the iconic green dome over Hz. Peygamber's burial chamber (painted green in 1837, having originally been white), rebuilding after a fire in 1481, and renovating extensively. The most dramatic transformation came under Saudi rule. The First Saudi Expansion (1951-1955) and Second Saudi Expansion (1985-1992) vastly increased the cami's capacity, introducing modern amenities including air conditioning, escalators, and the famous retractable umbrella canopies that shade the courtyard. The current cami covers approximately 400,000 square meters and can accommodate over one million worshippers during peak periods. The iconic ten retractable domes and the 250 umbrella canopies are engineering marvels unique to this cami.
Modern Masjid al-Nabawi is a breathtaking structure that seamlessly blends historical elements with contemporary engineering. The green dome, visible from throughout Medine, marks the location of Hz. Peygamber's burial chamber and the Rawdah. The cami is open 24 hours and includes namaz halls on multiple levels, underground parking facilities, cooling systems that manage temperatures for hundreds of thousands of worshippers, and advanced crowd management infrastructure. Despite its enormous scale, the cami retains an atmosphere of intimacy and devotion that hacilar consistently describe as unlike anywhere else. Hz. Peygamber's promise echoes across the centuries: 'A namaz in my cami is better than a thousand namazs elsewhere, except al-Mescid-i Haram.'
