The Messenger of Allah ﷺ said, "A prayer in this mosque of mine is better than a thousand prayers in any other mosque, except for the Sacred Mosque."
قال رسول الله ﷺ: صلاة في مسجدي هذا أفضل من ألف صلاة فيما سواه إلا المسجد الحرام.
Muslim narrated it in the chapter on Hajj (1395) through several routes from Yahya Qattan, from Ubaydullah, who said, Nafi informed me, from Ibn Umar, and he related it.
