Sayyiduna Salman al-Farisi (may Allah be pleased with him) wrote to Sayyiduna Abu al-Darda (may Allah be pleased with him): "My brother! Make the mosque your house, for I heard the Messenger of Allah (peace and blessings be upon him) say: 'The mosque is the house of every God-fearing person, and Allah, the Mighty and Majestic, has guaranteed to the one for whom the mosques are his houses comfort, mercy, and passage over the Bridge (al-Sirat).'"
