It is narrated from Sayyiduna Abu Basrah Humayl bin Basrah (may Allah be pleased with him) that he met Sayyiduna Abu Hurayrah (may Allah be pleased with him) while he was returning from al-Tur, and he said: "Had I met you before you went there, you would not have gone. I certainly heard the Messenger of Allah (peace and blessings be upon him) say: 'Mounts are saddled (for the purpose of travel) only to three mosques: the Sacred Mosque, this mosque of mine, and al-Masjid al-Aqsa.'"
