Ibn Mas'ud reported God’s Messenger as saying, “The food on the first day is a duty, that on the second is a sunna, but that on the third day is to make men hear of it; and if anyone makes men hear of what he does God will make him heard of” (i.e. will publish his hypocrisy on the day of resurrection).
Abu Huraira reported God's Messenger as saying, “The invitations of two people who are rivalling one another should not be accepted, and the food they provide should not be eaten.” The imam Ahmad said it means two people who are competing with one another in providing a feast out of self-glory and ostentation.
A companion of God’s Messenger reported him as saying, “When two people come together to issue an invitation accept that of the one who lives nearer you, but if one of them comes before the other accept the invitation of the one who comes first.”
