Lentils, cucumber and onion
Lentils in a dream can symbolize halal money as long as they are dry and not cooked.
The gathering of friends and scholars around the lenses suggests that a person from that place will die.
It is also said to indicate worries and subsistence of a lower standard, based on Allah’s statement:
“And when you said, ‘Moses! We will not put up with only one [sorts] food. So pray to your Lord for us that He may bring forth for us of what the earth produces, of its herbs, cucumbers, garlic, lentils and onions.” He said: “Will you exchange what is worse for what is better?” [82–61]
[abu Taher]
Anyone who sees someone taking herbs, onions, garlic and cucumbers symbolizes a person who has exchanged something better for something worse in the form of money or livelihood, knowledge, spouse or home.
