In an old market in the historic city of Tunis, Juha once set up a small sign that read: 'Wisdom for sale — one dirham a word.' A wealthy, arrogant merchant passed by and laughed mockingly, saying, 'Who would buy empty words, Juha?' Then, half-joking, he tossed him a coin and asked for a piece of wisdom.

Juha leaned in and whispered, 'Never trust anyone with your money until you have seen them keep their word before.' The merchant laughed at the saying and walked on, thinking it worthless.

Weeks later, a new business partner came to the merchant with dazzling promises of a profitable deal. The merchant lent him a large sum of money without ever asking about his reputation. The new partner soon vanished with the money, leaving the merchant with a great loss.

In that moment, the merchant remembered Juha's words and realized they had been true and precious wisdom, not empty talk as he had assumed. He hurried back to the market and found Juha sitting by his sign, just as before.

The merchant apologized and asked for more wisdom, this time with genuine humility and respect. Juha smiled and told him, for free this time, 'Judge people by their actions, not their promises — actions never lie.' He refused any payment, saying, 'It is enough for me that the lesson reached you.'

Word of Juha's wisdom spread throughout the markets of Tunis, and people began seeking him out not to mock him, but to learn from him. He continued sharing his wisdom generously, glad to spare others the mistakes he himself had once made.

The Lesson: A simple piece of wisdom can save us from great loss, and humility to learn from any source is a true virtue.
