The Prophet (may Allah's peace and blessings be upon him) commands us to mention Allah upon entering the house and before eating. When one mentions Allah saying: "Bismillāh" (in the Name of Allah) upon entering his house and before eating, the devil says to his companions: You shall not have a night shelter or supper in this house whose owner has sought protection against you by mentioning Allah Almighty. However, if one enters his house without mentioning Allah upon entering and before eating, the devil informs his companions that they will have a night shelter and supper in this house.
- It is recommended to mention Allah upon entering the house and before eating as the devil spends the night in the houses and eats from its dwellers' food if they do not mention the name of Allah Almighty.
- The devil is closely observing the son of Adam in his deeds, acts, and all his affairs. So, when one is heedless of Dhikr (remembrance of Allah), the devil achieves what he wants from him.
- Dhikr repels the devil.
- Every devil has followers and allies who rejoice at his words and follow his commands.
