Injustice in a dream indicates the ruin of homes and the loss of blessings. Whoever sees himself committing injustice will become poor. Whoever sees himself being wronged will be victorious over his oppressor.

Injustice indicates associating partners with God (shirk). It indicates worry and grief.
