Qarin - astral copy
Hamzad or Qarin: Jinn that is born alongside a human and who is his astral copy. He is the spirit that reveals the secrets to the magi about the person. That power is utilized by the magi after he has gained control over his own Qarin who will then communicate with the other Qarin and transfer information to the magi. To free himself from his Qarin a person must continually study the Quran, especially the verse al-Kursi, and the last two verses of surat Bekara.
