Musannaf Ibn Abi Shayba 27:889

Hushaym narrated to us, he said: Husayn ibn Abd al-Rahman informed us, from Muhammad ibn Talhah ibn Rukana al-Muttalibi, from Jubayr ibn Mut'im, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, a prayer in this mosque of mine is better than a thousand prayers in what is other than it, except for the Sacred Mosque (al-Masjid al-Haram)."
