It is narrated from Daylam al-Jayshani (may Allah be pleased with him); he said: I came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, we are in a land that is extremely cold, where we make a drink from wheat. Is it permissible to drink it?" He (peace and blessings be upon him) said: "Does it intoxicate you?" I said: "Yes." He (peace and blessings be upon him) said: "Then it is khamr (wine)."
