94. Chapter: On Honouring the guest
Allah says, "Has the story reached you of the honoured guests of Ibrahim? When they entered his dwelling and said, 'Peace! 'He said, 'Peace! O people unknown to us.' So he slipped off to his household and brought a fattened calf. He offered it to them. He exclaimed, 'Do you not then eat?'" (51:24-27)
Allah says, "His people came running to him excitedly. They were long used to committing evil acts. He said, 'O my people! Here are my daughters. They are purer for you. So fear Allah and do not shame me with my guests. Is there not one rightly-guided man among you?'" (W11:77; H11:78)
706. Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "Anyone who believes in Allah and the Last Day should honour his guest. Anyone who believes in Allah and the Last Day, should maintain ties of kinship. Anyone who believes in Allah and the Last Day, should speak well or be silent." [Agreed upon]
707. Abu Shurayh Khuwaylid ibn 'Amr al-Khuza'i said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'Anyone who believes in Allah and the Last Day should honour his guest as his due.' They said, 'What is his due, Messenger of Allah?' He said, 'A day and a night. Hospitality is for three days, and what is beyond that is sadaqa for him.'" [Agreed upon]
In a variant of Muslim, "It is not lawful for a Muslim to stay with his brother so long that he makes him fall into sin." They said, "Messenger of Allah, how can he make him fall into sin?" He said, "By staying with him when he has nothing to offer him."
