The history of the origin of the Sada festival in the immortal epic poem “Shahnameh” by the great poet Abulqasim Firdawsi

Once the King of the world set out toward the mountain
together with a few of his companions.

Suddenly, from afar, there appeared something long,
black in body and swift in movement.

Its eyes upon its head were like two bloody sources,
and from its mouth came smoke, and the whole world grew dark.

Hushang, the wise and discerning one, saw it,
and lifted a stone, throwing it with force.

With royal strength he swung his arm,
and the destructive serpent of the world leapt forward in a fierce attack.

The heavy stone struck another stone,
and both stones shattered apart.

And suddenly from those two stones a radiance appeared,
as the heart of the stone was filled with light.

The serpent was not killed, but by the secret will of fate
fire arose once again from the stone.

Whoever struck iron against stone
would draw from it light and a spark.

The ruler of the world, standing before the Creator of the world,
bowed in worship and gave thanks.

He said that this light was a divine gift,
and if one is wise, it must be honored.

Night came, and he lit a fire like a mountain of light,
and the king himself gathered his people around it.

That night he held a feast and drank wine,
and he named that blessed celebration Sada.

From Hushang remained the memory of Sada,
and many rulers after him as well,

who delighted the world with acts of creation,
and left behind a good and lasting name.

By the divine glory and greatness of the Kayanids,
he separated wild animals from domestic ones:

the cow, the donkey, and the sheep
he trained for benefit and labor.

The wise ruler Hushang said:
“Pair them together.”

And he taught people to make use of them,
to live and work alongside them.

From wild beasts—the sable, marten, and fox,
and also the soft-furred samur—

he used their pelts
to clothe the people.

He generously distributed and managed blessings,
and left behind nothing but a good name.

For forty years he lived in happiness and justice,
ruling the world with fairness.

He labored and reflected much,
but the time of his departure came.

And the world did not grant him a long life,
and the wise and glorious Hushang departed.

The world does not remain faithful forever,
nor does it always reveal itself to a person.
