Abu Uthman (may Allah be pleased with him) says: Sayyiduna Salman al-Farisi (may Allah be pleased with him) wrote to Sayyiduna Abu al-Darda' (may Allah be pleased with him): "O my brother! Let the mosque be your home, for I heard the Prophet (peace and blessings be upon him) say: 'The mosque is the home of every God-fearing person, and for those whose homes are the mosques, Allah Almighty has guaranteed comfort (rawh), mercy, and passage over the Sirat.'"
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Salih al-Murri, who is da'if (weak).
