Musnad Abu Ya'la al-Mawsili 149:119

Ibrahim narrated to us, Hammad narrated to us, from Dawud ibn Abi Hind, from al-Sha'bi, from Masruq, that Aisha said to al-Sa'ib: "You must abandon three traits, or I will surely confront you." He said: "And what are they?" She said: "Beware of rhymed prose (saj'), do not use rhymed prose, for the Prophet, peace and blessings of Allah be upon him, and his companions did not use rhymed prose. And if you come to a people who are talking, do not interrupt their conversation. And do not make people weary of the Book of Allah. And do not speak on Friday except once; but if you refuse, then twice."
