Mukhtasar Bukhari (Abridged) 621 — Virtue of praying in the mosques

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Offering one prayer in my mosque is better than offering a thousand prayers in other mosques, except for Masjid al-Haram (for the reward of praying there is greater)."
