Musnad Abu Ya'la al-Mawsili 42:192

Zuhayr narrated to us, Jarir narrated to us, from Mughirah, from Ibrahim, from Sahm ibn Minjab, from Qaza’ah, from Abu Sa’id, who said: The Messenger of Allah (peace and blessings of Allah be upon him) bade farewell to a man and said to him, "Where do you intend to go?" He said, "I intend to go to Bayt al-Maqdis (Jerusalem)." The Messenger of Allah (peace and blessings of Allah be upon him) said, "A prayer in my mosque is better than a hundred in any other, except the Sacred Mosque (al-Masjid al-Haram)."
