It is narrated in the books of Imams Al-Bukhari and Muslim that Anas Ibn Malik said:
"Some people of (the tribes of) 'Ukl and 'Uraynah came to Al-Madeenah and its climate did not suit them. So the Prophet ordered them to go to the herd of camels reserved for charity, and to drink their milk and urine (as a medicine). So they went as directed. After they became healthy, they killed the shepherds of the Prophet's camels and drove away all the camels, thus becoming aggressors against Allah All-Mighty and His Messenger . The Prophet, sallallaahu alayhi wa sallm, sent (men) in their pursuit and they were captured. The Prophet then ordered that their hands and feet to be cut off (and it was done), and their eyes were branded with heated pieces of iron. They were then kept in the sun until they died."
These people were complaining from dropsy, as per the narration from Imam Muslim who narrated the same narration above with the following addition: “…The Bedouins said: We have not found Al-Madeenah suitable for us and our stomachs swelled, our organs became weak..." until the end of the narration.
Dropsy is a physical disease that occurs when a harmful cold substance penetrates the external organs of the body and also the body organs other than those that are used in digestion, causing them to swell. There are three types of dropsy: in body tissue (fleshy), which is the most serious of the three, in a body cavity (ascites), and in an organ (drum). The remedy required for this disease includes mild laxatives and diuretic medicines that help rid the body of fluids. These diuretic qualities exist in the milk and urine of camels and that is why the Prophet ordered them to drink them. Camel milk is a mild laxative, diuretic, cleanses and opens that which is closed and removes the obstructions and soothes the body. This is especially the case when the camels graze on beneficial herbs, such as wormwood, lavender, chamomile, daisy and lemongrass. These herbs help against dropsy.
Dropsy is usually symptomatic of an ailment in the liver, especially due to congestion in the liver. The milk of the Arabian camels helps in this
case, because of its many benefits as mentioned and which help open the clogged passages and the obstructions. Ar-Razi said: "The she-camel's milk soothes the liver and the effects of a spoiled constitution." Al-Israeeli also said: "The she-camel's milk is the softest, least concentrated and lightest milk. It is the best choice for moving the bowels, as a laxative and for opening the clogged passages and obstructions. What makes this evident is the fact that this type of milk is mildly salty, as a result of the animal's instinctively hot nature. Therefore, the she-camel's milk is the best remedy for the liver as it soothes it, opens its pores and veins and softens the hardness of fresh food. Fresh, warm camel's milk is beneficial against dropsy, especially when taken with fresh, warm camel urine, thus making the combination more salty and adding strength to its effectiveness in dissolving harmful fluids and as a laxative. If the [combination of milk and urine] did not purge the stomach, then one should take a stronger laxative.” The author of Al-Qanoon also commented: "Do not listen to those who claim that milk does not provide cure from dropsy. Rather, know that camel's milk is an effective cure, because it cleanses gently and easily, due to its other qualities. This type of milk is so beneficial that if a person substituted water and food with camel's milk, he would be cured [from dropsy and other ailments]. Some people tried this remedy and were soon cured. We should state that the best camel urine is that of the camels of Bedouin people."
The story that was mentioned in the narration above has several areas of interest:
Assassination warrants capital punishment and cannot be pardoned [by the relatives of the deceased] or compensated, according to the scholars of Al-Madeenah, Imam Ahmad and Ibn Taymiyyah .
