Ibrahim Nakha'i narrated that I asked Aswad bin Yazid, "Did you ask Umm al-Mu'mineen Aisha (may Allah be pleased with her) about which vessel it is disliked to prepare nabidh (sweet date drink) in?" He said, "Yes, I asked, 'O Umm al-Mu'mineen! In which vessel did the Prophet (peace be upon him) forbid preparing nabidh?'" She said, "He forbade the household (Ahl al-Bayt) from soaking nabidh in gourds and varnished jars." (Ibrahim Nakha'i narrated that) I asked Aswad, "Did she not mention pitchers and green jars?" He said, "I am narrating to you only what I heard. Should I narrate to you what I did not hear?"
