in Islāmic mythology, two angels who unwittingly became masters of evil. A group of angels, after observing the sins being committed on earth, began to ridicule man's weakness. God declared that they would act no better under the same circumstances and proposed that some angels be sent to earth to see how well they could resist idolatry, murder, fornication, and wine. No sooner did Hārūt and Mārūt, the angels chosen, alight on earth than they were seduced by a beautiful woman. Then, discovering that there was a witness to their sin, they killed him. The angels in heaven were then forced to admit that God was indeed right, whereas the fallen angels faced atonement for their sins either on earth or in hell. Hārūt and Mārūt chose to be punished on earth and were condemned to hang by their feet in a well in Babylonia until the Day of Judgment.

Hārūt and Mārūt are first mentioned in the Qurʾān (2:102) as two angels purveying evil in Babylon, and the legend probably appeared to explain how they happened to be in that position. The story itself parallels a Jewish legend about the fallen angels Shemḥazaī, ʿUzza, and ʿAzaʾel. The names Hārūt and Mārūt appear to be etymologically related to those of Haruvatāt and Ameretāt, Zoroastrian archangels.
