Among the established Sunnahs of the Prophet: Remembering Allah upon entering the home. Jabir ibn 'Abdillah (may Allah be pleased with him and his father) reported: I heard the Prophet (peace and blessings of Allah be upon him) say: "When a man enters his house and remembers Allah Almighty upon entering and before eating, Satan says [to his companions]: 'You have no place to pass the night and no dinner.' But when he enters without remembering Allah upon entering, Satan says: 'You have found a place to pass the night.' And if he does not remember Allah before eating, he says: 'You have found both a place to pass the night and dinner.'" Recorded by Muslim.
