Sayyiduna Jabir bin Abdullah (may Allah be pleased with both of them) narrates that the Messenger of Allah (peace and blessings be upon him) said:“Recite «‏‏‏‏بسم اللہ» ‏‏‏‏ and close your door, for the devil does not open a closed door. Recite «‏‏‏‏بسم اللہ» ‏‏‏‏ and extinguish your lamp. Recite «‏‏‏‏بسم اللہ» ‏‏‏‏ and tie up your waterskin. And recite «‏‏‏‏بسم اللہ» ‏‏‏‏ and cover your vessel, even if you only place a stick across it.”
