Satan in Islam is neither an Angel nor any type of Angels!, he is just another creation of God called (Jinns) beside human beings (see the Quranic verses below).
"Behold! We said to the angels, “Bow down to Adam”: They bowed down except Iblis. He was one of the Jinns, and he broke the Command of his Lord. Will ye then take him and his progeny as protectors rather than Me? And they are enemies to you! Evil would be the exchange for the wrong-doers!"
"I have only created Jinns and men, that they may serve Me."
“And He created Jinns from fire free of smoke”.
However, in the Bible Satan is a fallen Angel, he was anointed Cherub which is a rank in the angelic hierarchy according to Christianity & Judaism, (Ezekiel 28:12-18), (2 Corinthians 11:14), (Revelation 12:3-9). (1) (2)
I have the following remarks on this topic:
- How Satan will be punished by fire (hell) when it’s made of fire!
- How come all the Prophets in the Bible did not mention that specie (Jinn) at all!
- If someone takes the Islamic claim that the Bible is corrupted, then what the Jews and Christians have gained by hiding that specie!
