Musannaf Ibn Abi Shaybah 25205 — Drinking camels' urine

It is narrated from Sayyiduna Tariq bin Shihab (may Allah be pleased with him), who said: A man had pimples break out on his neck, and he treated them with camels' urine and arak, in this way: camels' urine and arak were cooked together. People began asking this patient about the treatment, and the man refused to tell them. Then the man met Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), who said: Tell the people about this treatment.
