Masjid al-Nabawi was built by the Prophet Muhammad in 622 CE upon his arrival in Madinah. 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 the Prophet Muhammad (peace be upon him) arrived in Madinah during the Hijrah in 622 CE, one of his first acts was to build a mosque. 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 mosque 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 Makkah). The Prophet's apartments, shared with his wives, were built along the eastern wall. This humble structure served as the center of the Muslim community — a mosque, a school, a court, a parliament, and a social welfare center.
The mosque was expanded during the Prophet's lifetime as the Muslim community grew. After his death, Abu Bakr maintained the mosque 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 the Prophet's burial chamber within the mosque structure, introducing marble columns, gold mosaics, and minarets, and roughly doubling the mosque's area. This expansion set the architectural template for centuries.
The Ottomans invested heavily in the Prophet's Mosque over four centuries, adding the iconic green dome over the Prophet'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 mosque's capacity, introducing modern amenities including air conditioning, escalators, and the famous retractable umbrella canopies that shade the courtyard. The current mosque 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 mosque.
Modern Masjid al-Nabawi is a breathtaking structure that seamlessly blends historical elements with contemporary engineering. The green dome, visible from throughout Madinah, marks the location of the Prophet's burial chamber and the Rawdah. The mosque is open 24 hours and includes prayer 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 mosque retains an atmosphere of intimacy and devotion that pilgrims consistently describe as unlike anywhere else. The Prophet's promise echoes across the centuries: 'A prayer in my mosque is better than a thousand prayers elsewhere, except al-Masjid al-Haram.'
