Mukhtasar Muslim

Abu Huraira (may Allah be pleased with him) reports that the Prophet Muhammad (peace and blessings be upon him) said: "Mounts should not be saddled (i.e., journeys should not be undertaken) except towards three mosques: this mosque of mine (i.e., the mosque in Madinah, Masjid al-Nabawi), Masjid al-Haram, and Masjid al-Aqsa (i.e., Bayt al-Maqdis)."
