One day, King Hushang, the ruler of the world, journeyed toward the mountains accompanied by a retinue of his companions. Suddenly, from afar, a dark and swift-moving creature appeared—a monstrous black serpent whose two eyes burned like fountains of blood, and whose breath spewed thick smoke that darkened the sky. Observing the monster with wisdom and resolve, Hushang reached for a heavy stone, taking aim with his royal strength. He hurled the rock with fierce power; though the flame-breathing beast darted away unharmed, the stone struck another rock with mighty force. In that violent collision, a brilliant spark burst forth, setting the heart of the stone ablaze with light. The serpent fled into the shadows, but the secret of fire was revealed. Recognizing this heavenly glow as a divine gift, Hushang fell to his knees in adoration before the Creator of the World, praising the Divine for bestowing such a blessing upon mankind. He bade all wise souls to honor this sacred illumination. As night descended, a mountain of fire was ignited, and the king and his companions gathered around its warmth, feasting and rejoicing. Hushang christened that blessed night the Festival of Sadeh. Thus, the tradition of Sadeh remained as his everlasting legacy—a memorial to a sovereign who brought prosperity to the earth and was remembered for his goodness through all ages.
