Zuhayr narrated to us, Sulayman ibn Dawud al-Hashimi narrated to us, Ibn Abi al-Zinad narrated to us, from Musa ibn Uqbah, from Abu Abd Allah al-Quraz, from Sa'd ibn Abi Waqqas, that he heard the Prophet, peace and blessings of Allah be upon him, saying: "A prayer in this mosque of mine is better than a thousand prayers in what is other than it, except for the Sacred Mosque (al-Masjid al-Haram)."
