“I read in the letter of ’Abd Allah ibn Muhammad to abu al-Hassan (a.s.), in which he has said, ‘I pray to Allah to keep my soul in service for your cause. Zurarah has narrated for abu Ja’far, and abu ‘Abd Allah, ‘Alayhim al-Salam, about wine which pollutes one’s clothes that the two Imam had said, “It is not an offense to perform Salah (prayer) with such clothes. Only drinking wine is unlawful.” People other than Zurarah have narrated from abu ‘Abd Allah (a.s.). He (the Imam) has said, “If wine or al-Nabidh (a kind of wine) or any intoxicating thing pollutes your clothes, wash if you know the area of contact. If you do not know the area of contact, then wash all of such clothes. If you have performed Salah (prayer) with it perform such Salah (prayer) again.” Please instruct me which one I must follow. He (the Imam) wrote with his signature, “You must follow the words of abu ‘Abd Allah (a.s.).’”
