Narated By Zubayr ibn Uthman : The Prophet (pbuh) said: The wedding feast on the first day is a duty, that on the second is a good practice, but that on the third day is to make men hear of it and show it to them. Qatadah said: A man told me that Sa'id ibn al-Musayyab was invited (to a wedding feast on the first day and he accepted it. He was again invited on the second day, and he accepted.
