Virtue of praying in the Prophet's Mosque
Hadith Number: 929
وبهذا، عن رسول اللٰه صلی اللٰه علیه وسلم قال: والذی نفسی بیده لصلاة فی مسجد المدینة أفضل من ألف صلاۃ فیما سواه لیس الکعبة.
With this same chain, the Messenger of Allah (peace be upon him) said: "By Him in Whose hand is my soul! Offering one prayer in the mosque of Madinah (the Prophet's Mosque) is better than offering one thousand prayers in other mosques, except for the Ka'bah (the Sacred Mosque in Makkah)."
