"On answering the call of nature"
Mentioning the name of Allah before entering the toilet or taking off one’s clothes will prevent the jinn from seeing a person in a state of undress or harming him. The Prophet (peace and blessings of be upon him) says: “To put a barrier that will prevent the jinn from seeing the `awrah of the sons of Adam, let any one of you say ‘Bismillah’ when entering the toilet.”
