Islamic Interpretation of Dreams (Ibn-i Sirin):

(Chrysolite; Gem) In a dream, topaz represents a good man who is courageous, well behaved, a true friend, a pious person, or a religious person.

If topaz is understood to denote money in the dream, then it represents lawful earnings.

Topaz in a dream also represents the substance ofspeech, the essence of knowledge, and the good quality of a true human being.
