The Crop
Scholars have said that a known crop in a dream symbolizes the dreamer's actions in their religious or worldly life, with their reward or wealth depending on the crop's condition. Barley is considered better than wheat, signifying wealth with good health, and harvesting it on time indicates wealth subject to zakat. Rice, however, symbolizes wealth accompanied by hardship, trouble, and sorrow.
