Azrael: Angel of Death
However; the Zohar (the holy book of the branch of Judaism called Kabbalah) presents a more pleasant depiction of Azrael. The Zohar says that Azrael receives the prayers of faithful people when they reach heaven, and also commands legions of heavenly angels.
Although Azrael isn’t mentioned as the angel of death in any Christian religious texts, some Christians associate him with death because of his link to the Grim Reaper of popular culture. Also, ancient Asian traditions sometimes describe Azrael holding an apple from a "Tree of Life" to the nose of a dying person to separate that person’s soul from his or her body.
Some Jewish sages consider Azrael to be a fallen angel (a demon) who is the embodiment of evil. Islamic tradition describes Azrael as being completely covered in eyes and tongues, and the number of eyes and tongues constantly changes to reflect the number of people who are currently alive on Earth. Azrael keeps track of the number by writing the names of people in a heavenly book when they’re born and erasing their names when they die, according to Islamic tradition. Azrael is considered the patron angel of clergy and grief counselors who help people make peace with God before dying and minister to grieving people whom the dying have left behind.
