"The Messenger of Allah(ﷺ) said: ' Putting up a guest for one night is obligatory. If you find a guest at your door in the morning, then this (hospitality) is (like) a debt that you (the host) owe him. If he (the guest) wants, he may request it, and if he wants, he may leave it'"
Sunan Ibn Majah Book 33, Hadith 21
