A caliph once sent an expedition of horsemen and scholars into the far desert, searching for a legendary city said to be built entirely of brass, where jinn had been imprisoned since the time of Prophet Sulaiman. The party rode for many long days across vast stretches of sand until they finally reached towering walls gleaming beneath the sun.

The men searched for a gate to enter the massive city but found no key and no guard, until they discovered a hidden way through the walls. Once inside, they found the city entirely empty of any living soul, yet perfectly preserved just as its people had left it centuries before — grand palaces, golden statues, and silent, untouched markets.

In the heart of the city, they found writings carved into the walls warning every visitor against being deceived by worldly life, describing how the city's people had once been the strongest and wealthiest of all, only to meet the same fate as everyone else, leaving nothing behind but stone and memory. The men returned home carrying an unforgettable lesson: that all worldly glory eventually fades, and that the true legacy a person leaves behind is found only in good deeds.
