Benefits and Issues:
Benefit: This narration is weak in its chain of transmission.
Shaykh Abdul Tawwab Multani writes:
If the people eating on all three days are the same,
then the invitation on the third day is impermissible.
If they are different, then there is no harm in the abundance of days,
as this is established from the Salaf.
There is also an indication of this in Sahih al-Bukhari.

(Sahih al-Bukhari, Book of Marriage, Chapter: The Right of Accepting the Invitation to the Wedding Feast and the Invitation, and Whoever Held a Wedding Feast for Seven Days and the Like)
