Hadith 14:243
Abu Bakr narrated to us, he said: Al-Fadl narrated to us, he said: Sufyan narrated to us, from Qays ibn Muslim, from Tariq ibn Shihab, who said: There was a man who had scrofula (khanaazir), so they sought a cure with camel urine and arak (Salvadora persica). They would cook the camel urine and the arak. People began asking him [about the remedy], but he refused. Then Ibn Mas’ud met him and said: "Inform the people about it."
