Al-Masjid an-Nabawi is the second holiest mosque in Islam after Al-Haram in Mecca. Built by Prophet Muhammad in 622 AD, it houses his tomb beneath the iconic Green Dome. The mosque accommodates over one million worshippers and features remarkable architecture with retractable domes and automated umbrellas. Muslims from around the world visit year-round for prayers and spiritual reflection. The mosque complex includes the Rawdah, a sacred garden between the Prophet's tomb and his pulpit.
