Musnad Ahmad 33:319

Yahya narrated to us, from Ibn Jurayj, Ata’ narrated to us, from Jabir, from the Prophet, peace and blessings of Allah be upon him, who said: "Close your door and mention the name of Allah, for indeed the devil does not open a closed door. Extinguish your lamp and mention the name of Allah. Cover your vessel, even if by placing a stick across it, and mention the name of Allah. Tie your waterskin and mention the name of Allah."
