Seeking Wheat
Interpreters mention that whoever sees themselves seeking wheat, needing it, or touching it, might experience loss, humiliation, and dismissal if they are a ruler, and separation from their relatives. As for the seller of flour and barley, it was said that he is a man preoccupied with his own affairs and worldly matters.
