2. He who believes in Allah and the last day should honor his guest; he who believes in Allah and the last day should not annoy his neighbors; and he who believes in Allah and the last day should say what is good or keep silent. (Bukhari, Muslim)
3. It is part of the sunna that a man should accompany his guest to the door of the house. (IbnMajah)
4. He who believes in Allah and the last day should honor his guest. Provisions for the road are what will serve for a day and night; hospitality extends for three days; what goes beyond that is sadaqa; and it is not allowable that a guest should stay till he makes himself encumbrance. (Bukhari, Muslim)
5. Eat together and not separately, for the blessing is associated with the company. (IbnMajah)
