And Muhammad ibn al-Muthanna narrated to us, Muhammad ibn Ja'far narrated to us, Abdullah ibn Sa'id narrated to us, Salim Abu al-Nadr, the freed slave of Umar ibn Ubaydullah, narrated to us, from Busr ibn Sa'id, from Zayd ibn Thabit, who said: The Messenger of Allah, peace and blessings be upon him, enclosed a small chamber with a palm-leaf mat or a reed mat, and the Messenger of Allah, peace and blessings be upon him, came out to pray in it. He said: Then some men followed him and came to pray with his prayer. He said: Then they came one night and gathered, but the Messenger of Allah, peace and blessings be upon him, was delayed from them. He said: So he did not come out to them, and they raised their voices and threw pebbles at the door. Then the Messenger of Allah, peace and blessings be upon him, came out to them angry and said to them: "Your conduct has continued until I thought that it would be made obligatory upon you. So adhere to prayer in your houses, for the best prayer of a man is in his house, except for the prescribed prayer."
