Hazrat Abu Shuraih Ka’bi (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: Whoever believes in Allah and the Last Day should honor his guest. His hospitality is for one day and one night, and hosting is for three days and nights. Whatever is beyond that is charity. And it is not permissible for the guest to stay with his host so long that he causes him hardship.
