Is Iblees (Satan) one of the Jinn or one of the angels?

Question 523: Is Iblees (Satan) an angel or a Jinnee? And are the Jinn (creatures created from fire) his offspring or were he and his offspring created from them?

Answer: Iblees is one of the Jinn as Allaah (Exalted be He) says: And (remember) when We said to the angels: “Prostrate yourselves unto Aadam.” So they prostrated themselves except Iblees (Satan). He was one of the jinn; he disobeyed the Command of his Lord. He is not an angel. Moreover, he was created from fire while angels were created from light. This is mentioned in the Aayaat (Qur’aanic Verses) talking about the creation of Iblees. Besides, this is proven in the Hadeeth of the Messenger of Allaah (peace be upon him) narrated by `Aa’ishah (may Allaah be pleased with her) in which he said: Angels were created from light, Jinn were created from a smokeless flame of fire, and Aadam was created from that which you have been told (i.e., sounding clay like the clay of pottery) Related by Imaam Muslim in his Saheeh..read more here.
