Islamic Interpretation of Dreams (Ibn-i Sirin):

(Fire worshipper; Magi; Magus; Mazdaism; Sorcerer) Seeing an old man worshipping fire in a dream means facing a person who cares little about obliterating his enemy.

Seeing oneself worshiping fire in a dream means apostasy, committing adultery, theft, murder, making a false oath, polytheism, or being an unjust person.

Turning away from worshipping fire to embrace Judaism or Christianity in a dream means experiencing major changes in one’s life. Worshipping fire in a dream means desiring worldly pleasures. Worshipping the fire in a dream also means desiring to work for the ruler or a king, or it could mean going astray.

Ifthe fire one is worshipping is not lit in the dream, it means that he is seeking unlawful earnings.
