What is cupping therapy (Hijama)?
Wet cupping, or medical bleeding, is called Hijama in Arabic. The procedure is performed by drawing blood through suction from a small incision in the skin. It is one of the oldest and effective methods of releasing toxins from the body. Cupping relieves pain and pressure from the area in which it is performed by applying negative pressure; it helps in getting rid of negative pathogens by drawing out excess blood. Cupping helps in increasing blood circulation and it helps in the treatment of many health problems and also boosts the immune system.  
Prophetic method of performing Hijama
Here are a number of authentic narrations about cupping. 
In an authentic narration, Jaabir (may Allah be pleased with him) states that the Prophet (peace be upon him) said: “If there is any good in your medical treatments, it is in the knife of the cupper, drinking honey, or cauterization with fire, as appropriate to the cause of the illness, but I would not like to be cauterized.” 
According to a hadeeth (prophetic tradition) that was narrated by Anas ibn Maalik, may Allah be pleased with him, the Prophet (peace be upon him) said: “I did not pass by any group on the night when I was taken on the Night Journey (Isra’), but they said to me, ‘O Muhammad, tell your Ummah to do cupping.’” 
Ibn ‘Abbaas (may Allah be pleased with them both) reported that the Prophet (peace be upon him) was treated with cupping, and he paid the cupper his fee.” 
Anas ibn Maalik (may Allah be pleased with him) reported that the Messenger of Allah was treated with cupping by Abu Tayyibah. He commanded that he should be given two measures of food, and he spoke with his tax-collectors, who reduced his taxes. He said, “The best treatment you can use is cupping.” 
The best days for cupping
Various narrations state that the best days of the week for cupping are Monday, Tuesday, and Thursday while the best dates are the 17th, 19th and the 21st of the Islamic lunar month.
When talking about Islamic days, the night enters before the day. To illustrate what this means, Tuesday after sunset is when Wednesday night starts, therefore it is better to perform cupping during the daytime on any of the days or dates mentioned above.
Anas ibn Maalik (may Allah be pleased with him) reported that the Messenger (peace be upon him) said, "Whoever wants to perform cupping then let him search for the 17th, 19th and 21st." 
Ibn Umar (may Allah be pleased with them both) reported that the Messenger (peace be upon him) said, "Cupping on an empty stomach is best. It increases the intellect and improves the memory. It improves the memory of the one memorizing. So whoever is going to be cupped then (let it be) on a Thursday in the name of Allah.
Keep away from being cupped on a Friday, Saturday, and Sunday. Be cupped on a Monday or Tuesday. Do not be cupped on a Wednesday because it is the day that Ayub (Job) was befallen with a trial. You will not find leprosy except (by being cupped) on Wednesday or Wednesday night." 
If one is not able to be cupped on the 17th, 19th or 21st (coinciding with Monday, Tuesday or Thursday) then any Monday, Tuesday or Thursday of the month is fine.
Cupping while fasting or while in the state of Ihram
Abdullah ibn Abbas (may Allah be pleased with them both) reported that the Messenger (peace be upon him) was cupped on his head for a unilateral headache while he was in Ihraam. 
Abdullah ibn Abbas (may Allah be pleased with them both) reported that the Messenger (peace be upon him) was cupped while he was fasting. 
Anas ibn Maalik (may Allah be pleased with him) was asked: "Did you dislike cupping for the fasting person?" He said, "No, except for the reason of one becoming weak." 
It appears that cupping is allowed but disliked as Anas ibn Maalik (may Allah be pleased with him) mentioned because the fasting person becomes weak if they perform cupping, and Allah knows best.
Areas of cupping
Anas ibn Maalik (may Allah be pleased with him) reported that the Messenger (peace be upon him) was treated with cupping three times on the two veins at the side of the neck and the base of the neck. 
Abdullah ibn Abbas (may Allah be pleased with them both) reported that the Messenger (peace be upon him) was cupped on his head. 
Abdullah ibn 'Umar (may Allah be pleased with them both) reported that the Messenger (peace be upon him) used to cup his head and would call it (the place at the top of the head) "Umm Mugheeth." 
Cupping for women
Jaabir ibn Abdullah (may Allah be pleased with him) reported that Umm Salama (one of the wives of the Prophet, may Allah be pleased with her) asked permission from the Messenger (peace be upon him) to be treated with cupping so the Messenger (peace be upon him) ordered Abu Teeba (may Allah be pleased with him) to cup her. Jaabir ibn Abdullah (may Allah be pleased with him) said, " I think he (meaning the Messenger, peace be upon him) said that Abu Teeba (may Allah be pleased with him) is her brother through breastfeeding or was a young boy who didn't reach puberty". 
Who should do cupping for you?
Cupping should be done by an experienced professional. They should use equipment that is properly cleaned and sterilized or use new instruments for every client. It is important to make sure that the procedure is done properly and the cupper should make sure that no blood reaches the stomach of the patient.
