In Muslim it is added: Messenger of Allah (PBUH) said, "It is not permissible for a Muslim to stay so long with his brother till he makes him sinful." He was asked: "O Messenger of Allah, how can he make him sinful?" He replied, "He prolongs his stay with him till nothing is left with the host to entertain him (guest)."
Commentary: This Hadith throws light on something more of the etiquette and scope of hospitality. A guest ought to be given the best entertainment on the first day and night. For the next two days, hospitality should be moderate. On the fourth day, the guest should leave for his destination. Yet if he chooses to stay, hospitality will be in the sense of charity.
