question #1 Sahih Muslim 882b, Book 7, Hadith 90 : What is the significance of performing Nafl prayers at home after Jumu’a prayer?

He did not observe (Nafl) prayer after Jumu’a till he went back and observed two rak’ahs in his house. Yahya said: I guess that I uttered these words (before Imam Malik) that he of course observed (them).
