A fallen angel is a wicked or rebellious angel that has been cast out of Heaven. The term is found neither in the Hebrew Bible nor the Deuterocanonical Books nor the New Testament. Nonetheless, Biblical commentators often use fallen angel to describe angels who sinned or angels cast down to the Earth from the War in Heaven; Satan, demons, or certain Watchers. The term has also become popular in fiction and literature regarding angels.
Mention of angels who descended to Mount Hermon, (not "fell") to Earth is found in the Book of Enoch, which the Ethiopian Orthodox Church and Eritrean Orthodox Tewahedo Church accept as canonical, as well as in various pseudepigrapha.
Primary sources in relation to fallen angels 
Sons of God 
In the period immediately preceding the composition of the New Testament, some sects of Judaism identified the "sons of God" (בני האלהים) of Genesis 6:1-4 with fallen angels. Some scholars consider it most likely that this Jewish tradition of fallen angels predates, even in written form, the composition of Gen 6:1-4. Lester L. Grabbe calls the story of the sexual intercourse of angels with women "an old myth in Judaism". Indeed, until the mid-2nd century AD, Jewish writing (such as midrashim) can be taken to identify the "sons of God" of Gen 6:1 and 4 as angels. By the 3rd century, there is evidence that some early Christians accepted this Jewish Enochic pseudepigraphy and the application of the angelic descent myth to the "sons of God" passage in Genesis 6:1-4, Its presence not only in the East but also in the Latin-speaking West is attested by the polemic of Augustine of Hippo (354–430) against the motif of giants born of the union between fallen angels and human women. Rabbinic Judaism and Christian authorities rejected the tradition. Those who adopted the tradition viewed the "sons of God" as fallen angels who married human women and by unnatural union begot the Nephilim.[need quotation to verify]
Watchers, "Grigori" 
The reference to heavenly beings called "Watchers" originates in Daniel 4, in which there are three mentions, twice in the singular, once in the plural, of "watchers, holy ones". The Greek word for watchers is ἐγρήγοροι egrḗgoroi, pl. of egrḗgoros, literally "wakeful". Note that, beginning by AD 150, the Greek letter eta (η) was itacized to sound the same as iota (ι), and the Old Slavonic alphabets, both Cyrillic and Glagolitic, made no phonetic distinction between the letters they derived from Greek η and ι. The Greek term was transcribed in the Jewish pseudepigraphon Second Book of Enoch (Slavonic Enoch) as Grigori, referring to the same beings as those called Watchers of the (First) Book of Enoch.
First Enoch 
A Jewish myth of angels coming down to earth rather than being cast down, referred to as the myth of angelic descent, is found chiefly in the Jewish pseudepigraphic Book of Enoch, 6-9 and the Qumran Book of Giants and perhaps in Genesis 6:1-4. These Watchers became "enamored" with human women(1 Enoch 7.2), and had intercourse with them. The offspring of these unions, and the knowledge they were given, corrupted human beings and the earth(1 Enoch 10.11-12). A number of apocryphal works, including 1 Enoch (10.4) link this transgression with the Great Deluge.This myth was adopted by early Christianity, but abandoned by Rabbinic Judaism and later Christianity. During the period immediately before the rise of Christianity, the intercourse between these Watchers and human women was often seen as the first fall of the angels.
Slavonic Enoch 
The Slavonic Second Book of Enoch refers to "the Grigori, who with their prince Satanail rejected the Lord of light". The Grigori are identified with the Watchers of 1 Enoch. The Grigori who "went down on to earth from the Lord's throne", married women and "befouled the earth with their deeds", resulting in confinement under earth (2 Enoch 18:1-7) In the longer recension of 2 Enoch, chapter 29 refers to angels who were "thrown out from the height" when their leader tried to become equal in rank with the Lord's power (2 Enoch 29:1-4).
Most sources quote 2 Enoch as stating that those who descended to earth were three, but Andrei A. Orlov, while quoting 2 Enoch as saying that three went down to the earth, remarks in a footnote that some manuscripts put them at 200 or even 200 myriads. In The Old Testament Pseudepigrapha: Apocalypic Literature and Testaments edited by James H. Charlesworth, manuscript J, taken as the best representative of the longer recension, has "and three of them descended" (p. 130), while manuscript A, taken as the best representative of the shorter recension, has "and they descended", which might indicate that all the Grigori descended, or 200 princes of them, or 200 princes and 200 followers, since it follows the phrase "These are the Grigori, 200 princes of whom turned aside, 200 walking in their train" (p. 131).
Chapter 29, referring to the second day of creation, before the creation of human beings, says that "one from out the order of angels" or, according to other versions of 2 Enoch, "one of the order of archangels" or "one of the ranks of the archangels" "conceived an impossible thought, to place his throne higher than the clouds above the earth, that he might become equal in rank to [the Lord's] power. And [the Lord] threw him out from the height with his angels, and he was flying in the air continuously above the bottomless." In this chapter the name "Satanail" is mentioned only in a heading added in a single manuscript, the GIM khlyudov manuscript, which is a representative of the longer recension and was used in the English translation by R.H. Charles.
Fall of Satan 
The Hebrew Bible does not say that Satan is an angel, nor that he is fallen: it uses the corresponding Hebrew word, which means "adversary", of human opponents or some evil influence, but in three places it personifies Satan as a character, always inferior to God's power: it portrays him as an accuser (Zechariah 3:1-2), a seducer (1 Chronicles 21:1) or a heavenly persecutor (Job 2:1. In Jewish pseudepigrapha, especially apocalypses, he appears as the chief evil figure, "ruler of a demonic host, influencing event throughout the world, cast out of heaven as a fallen angel". Later texts present him as destined to be conquered by the angels or the messiah.
In Christianity also Satan, though capable of disguising himself as an "angel of light" (2 Cor 11:14), is the leader of the fallen angels. The New Testament mentions Satan 36 times in 33 verses, and the Book of Revelation tells of "that ancient serpent, who is called the devil and Satan, the deceiver of the whole world," being thrown down to the earth together with his angels. Luke 10:18 has Jesus say: "I saw Satan fall like lightning from heaven", a phrase that, according to Ben Witherington, can mean either "fall from heaven, like lightning" or "fall, like lightning from heaven".
A dragon and his angels 
In the New Testament, Revelation 12:3-14 speaks of a great red dragon whose tail swept a third part of the stars of heaven and cast them to the earth. In verses 7-9, after defeat in a War in Heaven in which the dragon and his angels fought against Michael and his angels, "the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world - he was thrown down to the earth, and his angels were thrown down with him." Thus, amongst Christians, fallen angels have been associated with the term “cast out”.[need quotation to verify]
Fall of Lucifer 
The fall of Lucifer finds its earliest identification with a fallen angel in Origen, based on an interpretation of Isaiah 14:1-17, which describes a king of Babylon as a fallen morning star (in Hebrew, הילל ). When this description was interpreted as regarding an angel, not a human king, the image of the fallen morning star or angel was applied to Satan both in Jewish pseudepigrapha[dubious ] and by early Christian writers, following the transfer of the Lucifer myth to Satan in the pre-Christian century. Origen and other Christian writers linked the fallen morning star of Isaiah 14:12 to Jesus' statement in Luke 10:18, "I saw Satan fall like lightning from heaven" and to the mention of a fall of Satan in Revelation 12:8-9. In Latin-speaking Christianity, the Latin word lucifer, employed in the late 4th-century AD Vulgate to translate הילל, gave rise to the name "Lucifer" for the angel believed to be referred to in the text.[dubious ]
Religious views 
The concept of fallen angels is first found in Judaism among texts of the Second Temple era, being applied in particular to Azazel and Satan. However, from the Middle Ages certain Jewish scholars, both rationalist and traditionalist, rejected belief in rebel or fallen angels, since they considered evil as simply the absence of good or at least as not absolute.
In Catholicism, the Catechism of the Catholic Church speaks of "the fall of the angels" not in spatial terms but as a radical and irrevocable rejection of God and his reign by some angels who, though created as good beings, freely chose evil, their sin being unforgivable because of the irrevocable character of their choice, not because of any defect in the infinite divine mercy.
In 19th-century Universalism, Universalists such as Thomas Allin (1891) claimed that Clement of Alexandria, Origen and Gregory of Nyssa taught that even the Devil and fallen angels will eventually be saved.
In Unitarianism, Joseph Priestley suggested that the passages refer to Korah. William Graham (1772) suggested that it referred to the spies in Canaan. These passages are generally held today to be commentary, either positive or neutral or negative, on Jewish traditions concerning Enoch circulating in the Early Church.
The Quran mentions angels (malak ملاك) around ninety times, usually in the plural and referring to obedient angels.
The Quran states that Satan was a jinn (as in Islam, angels cannot disobey God) and also he is mentioned with the angels in verses (2:34, 7:11, 15:29, 17:61, 18:50, 20:116, 38:71) prior to his fall. Satan (also called Iblis and in Greek diabolos, "the devil") rebelled and was banished on earth, and he vowed to create mischief on earth after being given respite by God till the Day of Judgment, according to verses (80-85:38). In Islamic terminology, jinns, like humans, have the capacity to choose whether to obey God or disobey him, which means they have free will.
Harut and Marut (Arabic: هاروت وماروت) are two angels sent to test the people of Babylon. That there are fallen angels is not in the Quran and the Quran explicitly states angels have no free will, but are like appendages of God. (Quran 2:30)
