History of the Prophets and Kings
A hadith in Book 4 ("Ablution") of al-Bukhari's collection narrated by Anas ibn Malik was used to promote the consumption of Arabian camel urine as a medicine. The Islamic prophet Muhammad is said to have advised some diseased people to use it "till their bodies became healthy." The authentic hadith also states "Some people of ‘Ukl or ‘Uraina tribe came to Medina and its climate did not suit them ... So the Prophet ordered them to go to the herd of (Milch) camels and to drink their milk and urine (as a medicine). ... So they went as directed and after they became healthy". Bukhari also narrated, an otherwise identical version of this Hadith, without the mention of "urine". The event has also been recorded in "Sahih Muslim", "History of the Prophets and Kings" and "Kitāb aṭ-ṭabaqāt al-kabīr."
