“Yunus and I were in Baghdad. I walked with him in the market. An owner of beer opened the container of his beer and drops from it came in contact with clothes of Yunus and I saw him depressed until it became Zawal (declining of the sun toward the west at noontime). I asked him, ‘O abu Muhammad, do you want to perform Salah (prayer)?’ He said, ‘I do not want to perform Salah (prayer) until I return home and wash this wine from my clothes.’ I then said, ‘Is this your opinion or it is something you narrate.’ He said, ‘Hisham ibn al-Hakam has narrated that he asked abu ‘Abd Allah (a.s.), about beer. He (the Imam) said, ‘Do not drink it; it is unknown wine. If it pollutes your clothes, wash them clean.’”
