It is narrated from Sayyiduna Abu Shurayh that the Prophet (peace and blessings be upon him) said: Hospitality is for three days, and the right (of special hospitality) is only for one day and one night. And it is not permissible for any man to stay with someone so long that he makes him sinful. The people asked: O Messenger of Allah! How will he make him sinful? He said: He stays with him while he has nothing left for hospitality.
