Yes. The jinn are a real, unseen creation whom Allah made from a smokeless flame of fire, just as He made mankind from clay, and like humans they are morally accountable — commanded to worship Allah alone and divided into believers and disbelievers. An entire chapter of the Quran, Sūrat al-Jinn, records a group of them accepting faith after hearing the Quran. Denying their existence is a rejection of what Allah has plainly affirmed, and it is forbidden to worship them or seek refuge in them, since the pagans went astray by taking jinn as partners with Allah.
