Abu Ishaq says that one day people began to discuss in which vessels Nabidh can be made. During the conversation, there was a difference of opinion regarding Nabidh in a gourd vessel. Coincidentally, Hazrat Abu Ayyub Ansari (may Allah be pleased with him) passed by, so they sent a man to ask him about it: "O Abu Ayyub! What is the ruling on Nabidh in a gourd vessel?" He replied, "I heard the Prophet Muhammad (peace be upon him) forbid making or drinking Nabidh in any vessel that is coated with pitch." The questioner asked specifically about the gourd, and he gave the same answer again.
