Islamic Interpretation
In a vision, locusts symbolize an affliction, a test, a disaster, or divine chastisement. They may also represent ruinous rainfall or invasion by a fierce military force. Eating locusts signifies receiving money. Filling a cup or pitcher with them also denotes income. Locusts entering a place without causing damage means overcoming trials. If a wealthy person who has lost his fortune sees a swarm of locusts descending upon him, it means he will recover his wealth.
