Al-Ḥāriṯ (literally: the lion, the ploughman, or the light-bringer, anglicised as Ateras, Atheras, Eosphorus, Phosphorus, and Lucifer), known as Azazil (literally "the Dear of God", anglicised as Azezel), is the Satan from Islamic scriptures. He was pious genie and due to that he ascended from his demonic state as one of jinn to worship Allah with his angels; however, when he has refused to prostrate for Adam he transformed into something worse and more demonic and became the father of devils.
In the Quran[]
Al-Harith is never mentioned by his name in the Quran but in the Sunnah, instead: he is mentioned by the title Iblis which translated directly as Satan or al-Shaitan (the Devil)
Chapter 15 verse 28-44[1]
Waith qala rabbuka lilmalaikati innee khaliqun basharan min salsalin min hamain masnoonin ( 28 )

To it are seven gates: for each of those gates is a (special) class (of sinners) assigned.
As a fallen angel[]
Some said al-Harith was paradisiac angel, Watcher, cherub, or seraph before his dismissal from paradise; then, he turned into a devil, genie, or devilish genie.
Some people mistakenly thought jinn were the angels of paradise and considered jinn as type of angels or fallen angels.
He possibly born as a genie then turned into angel then fall from his grace.
But unlike Christian fallen angels, Islamic fallen angels are redeemable and can get their graces back.
As a genie[]
He was either born as a genie then turned into devil, or born as angel then transformed into a genie as punishment for his wrong deeds. In other stories he has always been a genie and never been an angel.
In Yazidism[]
There is an angel similar to Iblis in Yazidi mythology called: Peacock Angel;. Such angels are ordered by God to prostrate for Adam all angels prostrated but Peacock Angel refused because he doesn’t want to prostrate for anyone rather than God. Due to that, he was promoted to the leader of angels as a reward; unlike al-Harith, he hasn’t become Iblis or anything like that.
In Sufism[]
Al-Harith is either another name of Marra, his son, or his father.
