Narrated Abu Shuraih Al-Adawi: My ears heard and my eyes saw the Prophet when he spoke, "Anybody who believes in Allah and the Last Day, should serve his neighbor generously, and anybody who believes in Allah and the Last Day should serve his guest generously by giving him his reward." It was asked. "What is his reward, O Allah's Apostle?" He said, "(To be entertained generously) for a day and a night with high quality of food and the guest has the right to be entertained for three days (with ordinary food) and if he stays longer, what he will be provided with will be regarded as Sadaqa (a charitable gift). And anybody who believes in Allah and the Last Day should talk what is good or keep quite (i.e. abstain from all kinds of dirty and evil talks).

Narrated Abu Shuraih Al-Ka`bi: Allah's Apostle said, Whoever believes in Allah and the Last Day, should serve his guest generously. The guest's reward is: To provide him with a superior type of food for a night and a day and a guest is to be entertained with food for three days, and whatever is offered beyond that, is regarded as something given in charity. And it is not lawful for a guest to stay with his host for such a long period so as to put him in a critical position." Narrated Malik: Similarly as above (156) adding, "Who believes in Allah and the Last Day should talk what is good or keep quiet." (i.e. abstain from dirty and evil talk, and should think before uttering).

Narrated Abu Shuraih Al-Khuza`i: My ears heard and my heart grasped (the statement which) the Prophet said, "The period for keeping one's guest is three days (and don't forget) his reward." It was asked, "What is his reward?" He said, "In the first night and the day he should be given a high class quality of meals; and whoever believes in Allah and the Last Day, should entertain his guest generously; and whoever believes in Allah and the Last Day should talk what is good (sense) or keep quiet."
