My own eyes saw the Messenger of Allah ﷺ and my own ears heard him when he said, "Whoever believes in Allah and the Last Day should honor his guest with his special hospitality."They asked, "What is his special hospitality?"He replied, "A day and a night. Hospitality extends to three days, and whatever is given beyond that is charity. And whoever believes in Allah and the Last Day should speak good or remain silent."
حدثنا قتيبة حدثنا الليث بن سعد عن سعيد بن أبي سعيد المقبري
أبصرت عيناي رسول الله ﷺ وسمعته أذناي حين تكلم به قال من كان يؤمن بالله واليوم الآخر فليكرم ضيفه جائزته قالوا وما جائزته قال يوم وليلة والضيافة ثلاثة أيام وما كان بعد ذلك فهو صدقة ومن كان يؤمن بالله واليوم الآخر فليقل خيرا أو ليسكت
