Islamic Interpretation of Dreams (Ibn-i Sirin):

(Business) Ifone’s losses relate to his earnings, then his losses in the dream mean decadence of one’s principals, religious downswing, or they could mean heedlessness after guidance, disbelief after following one’s religion, or losses in general.

This sin is man’s own.

Ifone suffers a loss in a dream, it means dismay, horror, a scare, a shock or a menace. Complaining about a harm one suffers, a damage or a loss in a dream means attaining one’s goal.
