Question 254: Is Iblees (Satan) one of the Jinn (creatures created from fire) or one of the angels?
Answer: Iblees is one of the Jinn, not the angels, as Allaah 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 (Soorah Al-Kahf, 18: 50) Allaah also says, He created man (Aadam) from sounding clay like the clay of pottery. And the jinn: He created from a smokeless flame of fire. (Soorah Al-Rahmaan, 55: 14-15) The Prophet (peace be upon him) said, The angels were created out of light; Iblees was created out of a spark of fire; and Aadam was created as he has been defined (in the Qur’aan) for you. Narrated by Muslim. Al-Hasan Al-Basree said that Iblees had never been an angel; he is the father of Jinn just as Aadam is the father of human beings. Narrated by Ibn Jareer with an authentic Isnaad (chain of narration). However, Iblees disobeyed the orders, as he was with the angels and imitated them in their ‘Ibaadah (worship), so he was included in the address directed to them and disobeyed Allaah’s order of Sujood (Prostration)…. read more here.
