«أَبُو مِيَّةْ يِحْسِدْ أَبُو تْنِيَّهْ»

Having plenty does not always put an end to envy. The person with a large flock still covets the single sheep belonging to someone with far less.

The proverb criticizes greed that turns even a small possession into an object of jealousy. Its contrast makes the richer person's resentment appear especially petty.

Use it to criticize someone who has much more than another person but still begrudges that person a modest possession or advantage. The point is the envy, not merely the difference in wealth.
