Sayyiduna Abu Basrah al-Ghifari (may Allah be pleased with him) said: I met Sayyiduna Abu Hurayrah (may Allah be pleased with him) and said to him: I heard the Messenger of Allah (peace and blessings be upon him) say: "Mounts are not to be saddled except for three mosques: my mosque, al-Masjid al-Haram, and al-Masjid al-Aqsa."
