Abu Al-Alaniyah (may Allah have mercy on him) says that I asked Hazrat Abu Saeed Khudri (may Allah be pleased with him) about the nabidh (fermented drink) made in a pitcher, so he replied that the Prophet (peace and blessings be upon him) forbade it. I asked, "What is the ruling about a hollow piece of wood?" He replied, "That is even worse than the pitcher."
