A'yan al-Khwarizmi said, "We came to Anas ibn Malik while he was
sitting his foyer with anyone else with him. My companion greeted him and
said, 'May I come in?' Anas said, 'Come in. This is a place where no one
asks for permission.' He had food brought to us and we ate. Then a cup
of sweet nabidh was brought and we drank and were full."
Jabir reported that the Prophet, may Allah bless him and grant
him peace, said, "When a man enters his house, he should Allah mention
Allah Almighty, both when he enters and he eats. If he does so, Shaytan
says (i.e. to the shayatin), 'You cannot spend the night or eat.'
When he enters and does not mention Allah when he enters, Shaytan says,
'You have got your lodgings for the night and your supper.'"
