Musannaf Ibn Abi Shaybah

Hazrat Maymunah (may Allah be pleased with her), the Mother of the Believers, narrates that I heard the Messenger of Allah (peace and blessings be upon him) say: Offering one prayer in this mosque of mine — that is, in the Prophet’s Mosque ﷺ — is better than a thousand prayers in any other mosque, except for the mosque of Makkah. Imam Abu Bakr (may Allah have mercy on him) says: The people of Egypt have also narrated this hadith, but in their chain of narration, the mention of Ibn Abbas (may Allah be pleased with them both) is not included.
