Muhammad bin Khazim al-Darir محمد بن خازم أبو معاوية الضرير · Foods (Kitab Al-At'imah)

When a man enters his house and mention Allah’s name on entering and on his food, the devil says: You have no place to spend the night and no evening meal; but when he enters without mentioning Allah’s name on entering, the devil says: You have found a place to spend the night, and when he does not mention Allah’s name at his food, he says: You have found a place to spend the night and an evening meal.

When one of you eats, he must not wipe his hand with a handkerchief till he licks it or gives it to someone to lick.
