Angels-SHAITANS

Shaitans (also Shaytans) are evil spirits with cock’s feet found in
Hebrew and Arabic mythology. In the Islamic faith, angels guard the
walls of heaven to prevent shaitans and other evil spirits from eavesdropping.
When one shaitan appeared before Muhammad, however,
the prophet began to teach the spirit from the Koran so that he might
reconcile with God. Shaitan is also an alternate name for Iblis (Satan).
