Up until the time of my writing and compiling this book, I have only found this famous poem of his, well-known among the 'Initiated' (al-muwassidīn): 'O you who know of your era that which is obligatory.' It is among the finest poetry regarding Monotheism; he cloaked the wisdom within it with the most beautiful veil. Most of it consists of ancient issues with subtle, precise meanings.

And among the Gnostic Monotheists is Ḥaydara al-Qaṭī‘ī. He is the son of Abū al-Fatḥ Muḥammad ibn al-Ḥasan ibn Muqātil al-Qaṭī‘ī al-Baghdādī, and he was the brother [in learning/hearing] of the Emir ‘Iṣmat al-Dawla, may Allah be pleased with him. This Ḥaydara has many poems, and among his sayings—may Allah be pleased with him—is:"

"I bear witness that the Deity of creation is Ali,

The turner of what is within the hearts.

Allah is not veiled from His creation;

Rather, they are veiled [from Him] by their sins.

And if only they had believed and been pious,

They would have become angels in the realms of the Unseen.

Wandering through the Kingdom of the Ancient One,

Having been purified of every sin."

"If it were not for our desire to include others, we would have presented more of his poetry, which delights both listener and reader.
