A camel is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). As working animals, camels—which are uniquely suited to their desert habitats—are a vital means of transport for passengers and cargo.
Camel urine, like other halal livestock, is not najis. However, in general it is haram to drink its urine, according to obligatory precaution.
It would be permissible to consume only if it can cure an illness, and limited only to that, enough for the cure. This means that a cure is limited to this exclusively, and the amount consumed is enough for that purpose only.
And Allah knows best.
Drinking human urine is definitely forbidden (Haraam) because it is Najis (impure) and consuming any Najis (impure) item is absolutely Haraam.
There is no question of drinking your own urine for medical reasons, because it is Najis and no cure can come from Najis item as the Hadeeth states ( Allah The Glorious never puts cure in anything which has been forbidden by Him).
Drinking the urine of camels is mentioned in many Sunni books like Bukhari, ( Vol.1, Page 62,
Ibn Maajah 2/1158,
Mussannaf Ibn Abi Shaibah 5/455, etc.
It is also mentioned in some Shia books with the condition of medical need.
It must be noted that camels’ urine is not Najis, because of the fact that the urine of any animal which is allowed to be eaten by us (Halal) is not Najis.
