Nafi' said: Ibn Umar used to lengthen his prayer before the Friday prayer and would offer two rak'ahs after it in his house. He used to say that the Messenger of Allah (ﷺ) would do that.
Sunan Abi Dawud Book 2, Hadith 739
← Previous Hadith Ibn 'Umar saw a man praying two rak'ahs after the Friday prayer on the same place (where he offered the Friday prayer). He pushed him and said: Do you offer four rak'ahs of Friday prayer ? 'Abd Allah (b. 'Umar) used to pray two rak'ahs in his house after the Friday prayer, and he used to say: This is how the Messenger of Allah (ﷺ) did.

Sunan Abi Dawud Book 2, Hadith 738 Next Hadith → I offered the Friday prayer along with him in enclosure. When I uttered the salutation I stood up in my place and prayed. When he went in, he sent me a message saying: Never again do what you have done. When you pray the Friday prayer, you must not join another prayer to it till you have engaged in conversation or gone out, for the Prophet of Allah (ﷺ) gave the precise command not to join on prayer till you have engaged in conversation or gone out.
