Islamic Interpretation of Dreams (Ibn-i Sirin):

(Balance; Measure) Seeing a scale in a dream means renewal of one’s business. Depending one the truthfulness by which one weighs his business, or product, a scale in a dream also means profits or a fine. Receiving a scale as a gift in a dream means that one may become ajudge.

The same applies if one sees himself transformed into a scale in a dream.

If one sees merchants short weighing their merchandise in a dream, then a scale will represent ajudge who deviates from justice.
