Abu Shurayh al-Kabi al-Adawi (ra) has reported that the Messenger of Allah (ﷺ) said, "He who believes in Allah and the last day should speak a good, decent conversation otherwise remain silent. And he who believes in Allah and the last day should honour his guest whose Jaizah (a provision for the guest better than one’s own meals) is the length of a day and a night. And hospitality extends for three days and whatever is beyond that (more than three days) is Sadaqah. it is not proper for a guest to tax his host by overstaying (so that he is tired of him).
