Michael is mentioned three times in the Hebrew Bible (the Old Testament), all in the Book of Daniel. The prophet Daniel experiences a vision after having undergone a period of fasting. Daniel 10:13-21 describes Daniel's vision of an angel who identifies Michael as the protector of Israel. At Daniel 12:1, Daniel is informed that Michael will arise during the "time of the end".

The Book of Revelation (12:7-9) describes a war in heaven in which Michael, being stronger, defeats Satan. After the conflict, Satan is thrown to earth along with the fallen angels, where he ("that ancient serpent called the devil") still tries to "lead the whole world astray".
In the Epistle of Jude 1:9, Michael is referred to as an "archangel" when he again confronts Satan.
A reference to an "archangel" also appears in the 4:16. This archangel who heralds the second coming of Christ is not named, but is often associated with Michael (among others).
Michael (Arabic: ميخائيل, Mikhail ميكائيل, Mikail ), is one of the two archangels mentioned in the Quran, alongside Jibrail (Gabriel). In the Quran, Michael is mentioned once only, in Sura 2:98: "Whoever is an enemy to God, and His angels and His messengers, and Jibrail and Mikhail! Then, God (Himself) is an enemy to the disbelievers." Some Muslims believe that the reference in Sura 11:69 is Michael, one of the three angels who visited Abraham.
