Re: Do jinns exists
18:50 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!
7:12 ((Allah)) said: “What prevented thee from bowing down when I commanded thee?” He said: “I am better than he: Thou didst create me from fire, and him from clay.”
Hence, from Quran, I conclude that Jinn are made of fire and they are a separate creature of Allah:swt:
