In the Name of Allah the most Beneficent and Merciful.
It is mentioned in the Quran that Iblis was made of Fire, but it is also mentioned that All Angels prostrated except him. There is thus a divided scholarly opinion on this issue. The majority of the scholars are upon the view that he was a Jinn, but some do mention that he was an Angel. However, we know he is damned and cursed by Allah. (This fatwa has been mentioned by Mufti Ahmad Yaar Khan Naeemi Rehmutallah Alaih in his Fatawa-e-Naeemiya)
Of course Allah knows best
