Masjid an-Nabawi, often referred to as the Prophet’s Mosque, is one of the holiest and most revered places in Islam. Located in the city of Medina, Saudi Arabia, it was originally built by the Prophet Muhammad himself in 622 CE, shortly after his migration (Hijra) from Mecca. Over the centuries, the mosque has been expanded and renovated several times, transforming into a grand architectural marvel capable of hosting millions of worshippers annually.

The mosque’s most prominent feature is the Green Dome, which marks the resting place of the Prophet Muhammad, along with his close companions, Abu Bakr and Umar. The Rawdah, or "Garden of Paradise," situated between the Prophet’s tomb and his pulpit, is a particularly sacred spot where Muslims offer prayers, as it is believed to be one of the gardens of Paradise mentioned in Islamic tradition.

Masjid an-Nabawi is also famous for its stunning architecture, featuring large open courtyards, intricately designed domes, and towering minarets. During daily prayers and especially during the Hajj and Ramadan seasons, millions of Muslims gather to worship in its vast prayer halls, which can accommodate more than a million worshippers at once. The mosque holds a central place in the lives of Muslims, as visiting it is a highly recommended act during the pilgrimage to Mecca. It is second in sanctity only to Masjid al-Haram in Mecca.

This name reflects the mosque's spiritual significance as a place of illumination, both in terms of faith and in its connection to the life and teachings of the Prophet Muhammad. The name also underscores its role as a center of guidance for millions of Muslims who visit it.
