Masjid-e-Nabwi is the masjid (mosque) established by the Prophet (s.a.w.) upon his migration to Madinah. It is the second most revered masjid in Islam and the second largest in the world, after Masjid al-Haram in Makkah.
“O Allah, no good is but the good Hereafter, So help the Helpers and the Emigrants.” And sometimes they chanted: “No life there is but the life of the Hereafter. Mercy, O Allah, on Emigrants and Helpers.”
The masjid was built twice during the lifetime of the Prophet (s.a.w.). The first time was shortly after he had made the Hijra to Madinah in 622 CE, with the size of the masjid being approximately 35 x 30 meters and the height 2.5 meters. It was rebuilt seven years later after the Fath (opening) of Khaibar. The increasing number of Muslims by then necessitated an increase in the area of the mosque to accommodate more worshippers. Usman (r.a.) paid for the land to accommodate the extension which made the masjid approximately 50 x 50 meters. The height was also increased to 3.5 meters.
“Whoever performs forty salat in my masjid, not missing one salat in the masjid, for him is granted exemption from the fire of Hell, and exemption from punishment and he shall remain free of hypocrisy.” [Ahmad]
“One salat offered in my masjid is superior to one thousand salats offered in other masjids except Masjid al-Haraam (Makkah al-Mukarramah).” [Bukhari]
