Harut
Harut and Marut (Arabic: هاروت وماروت) are two angels mentioned in the second Surah of the Qur'an, who were sent down to test the people at Babel or Babylon by performing deeds of magic. (Sura Al-Baqara, verse 102). The Qur'an indicates that although they warned the Babylonians not to imitate them or do as they were doing, some members of their audience failed to obey and became sorcerers, thus damning their own souls.
