Musannaf Ibn Abi Shaybah 34703 — The mosque of Madinah

Sayyidah Maymunah (may Allah be pleased with her), the Mother of the Believers, said: "I heard the Messenger of Allah (peace and blessings be upon him) say: 'A single prayer in this mosque of mine (that is, the mosque of the Prophet (peace and blessings be upon him)) is better than a thousand prayers in any other mosque, except the mosque of Makkah.'"
