Sayyiduna Abu Shurayh al-Adawi (may Allah be pleased with him) said: My ears heard and my eyes saw when the Messenger of Allah (peace and blessings be upon him) said this: "Whoever believes in Allah and the Last Day, let him honour his guest, (giving) his special hospitality." The people said: O Messenger of Allah, what is his special hospitality? He (peace and blessings be upon him) said: "One day and one night, and hospitality is three days; whatever is beyond that is charity from the host to him. And he should not stay with him so long that he has to put him out." And he said: "Whoever believes in Allah and the Last Day, let him speak good or remain silent."
