It was narrated that Miqdam Abu Karimah said:
"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'"
