Sayyiduna Imam al-Hasan bin Ali bin Abi Talib (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Pray (voluntary) prayers in your houses and do not make them graveyards, and do not make my house a place of festivity. Send blessings and peace upon me; your blessings and your peace will reach me wherever you may be."
Abu Ya'la recorded it; its chain contains Abdullah bin Nafi', who is da'if (weak).
