Musnad Abu Ya'la al-Mawsili 160:163

Muhammad ibn al-Minhal narrated to us, Yazid ibn Zuray' narrated to us, Rawh narrated to us, from Zayd ibn Aslam, from Sa'id ibn Abi Sa'id al-Maqburi, that Abu Basrah Jamil ibn Basrah met Abu Hurayrah while he was coming from al-Tur. He said: "Had I met you before you went to it, you would not have gone to it. I heard the Messenger of Allah (may Allah bless him and grant him peace) saying: 'The flanks of mounts are struck [i.e., journeys are undertaken] to three mosques: the Sacred Mosque, this mosque of mine, and the Furthest Mosque.'"
