There are total 9 points of the body where Prophet Muhammad Sallallaho Alaihe Wasallam were performed hijamah. These are the sunnah points of Hijamah.
In Ghazwah Khyber while our beloved Prophet Muhammad s.a.w was poisoned, he took Hijamah at 3 points on the KAHIL, we feel that a cup was applied behind the heart (at the left of KAHIL), & the third was either a little bit lower to this point OR on the right side of KAHIL, Allah Knows the best.
Abdul Razzaq narrated that, “A Jewish woman brought to Prophet Muhammad Sallallaho Alaihe Wasallam a roasted sheep that she had poisoned, while he was in Khyber. Our beloved Prophet asked, ‘What is this, She said, a gift, being careful not to say that it was from charity so that he would not eat it. Prophet Muhammad Sallallaho Alaihe Wasallam and Sahabah (his companions) ate from the sheep, then our beloved Prophet said, “Stop eating”. He said to the woman, ‘Did you poison this sheep?’ She said, “Who told you that” ? He said, this bone,’ meaning the ewe’s leg that he had in his hand. She said, “Yes”. He said, ‘Why?’ She said, I thought that if you were a liar, the people would be relieved from you. However, if you were a true Prophet, it would not harm you.’ Prophet Muhammad Sallallaho Alaihe Wasallam then used HIJAMAH (cupping) thrice on the KAHIL (upper part of his back) and commanded that his Companions do the same. Yet, several of them died.”
Narrated by Ibn Majah, on the authority of Ali Radi Allaho Anh that angel JIBREEL advised Prophet Muhammad Sallallaho Alaihe Wasallam for Hijamah at Akhda’ain (posterior jugulars) and KAHIL (upper back ~ between the shoulders).
Reported by Abu Kabshah Al Anmari Radi Allaho Anh that Prophet Muhammad Sallallaho Alaihe Wasallam took Hijamah on Haamah & between the shoulders (which is KAHIL). Narrated by Abu Dawood & Ibn-e-Majah
Reported by Abdullah Bin Bujainah Radi Allaho Anh that Prophet Muhammad Sallallaho Alaihe Wasallam took Hijamah on the center of his head (Yafookh) and he was in Ehraam while his journey to Makkah. (Name of the place where they stopped is mentioned as Lahyi Jamal)
“Use Hijamah (wet cupping) on the Qamahduwah (above the nape cavity), for it cures seventy two kinds of ailments”. (Narrated by Tabraani)
Abu Dawood narrated that Jabir Radi Allaho Anh said that Prophet Muhammad Sallallaho Alaihe Wasallam used Hijamah (wet cupping) on his hip because of a debilitation he suffered from.
Prophet Muhammad Sallallaho Alaihe Wasallam also took Hijamah on the hip & top of his foot, which explains that Hijamah at the painful area is also recommended by Tibb-e-Nabawi.
Reported by Anas Radi Allaho Anh that (while in Ehraam), Prophet Muhammad Sallallaho Alaihe Wasallam took Hijamah on the top of his foot due to the pain in that area. Narrated by Abu Dawood
