It is narrated from Sayyiduna Miqdam bin Ma'dikarib, may Allah be pleased with him, that he heard the Prophet, peace and blessings be upon him, say: "It is obligatory upon every Muslim to take care of the guest for one night. If the guest remains deprived in the courtyard of his host until morning, then the host has become indebted to him; if he wishes, he may repay it, and if he wishes, he may leave it."
