Sayyidina Abu Shurayh Adawi narrated: My eyes saw Allah’s Messenger (SAW) and my ears heard him when he spoke. He said, “One who believes in Allah and the Last Day must honour his guest and serve him his jaizah.” The sahabah asked him what his jaizah was. He said, “A day and a night.” He added, “And the hospitality is for three days what is beyond that is sadaqah. And he who believes in Allah and the Last Day must speak a good word, or keep quiet.” (Jaizah is provision of a traveler).
