Hakim Abul-Majd Majdūd ibn Ādam Sanā'ī Ghaznavi, commonly known as Sanā'ī, was a pioneering Persian poet and Sufi mystic born in the city of Ghazni, located in present-day Afghanistan. He is celebrated for his profound influence on Persian literature, particularly through his introduction of mystical and ethical themes into Persian poetry.

Sanā'ī's most renowned work, Ḥadīqat al-Ḥaqīqat wa Sharīʿat al-Ṭarīqat (The Walled Garden of Truth and the Law of the Path), commonly referred to as Ḥadīqa, is a seminal piece in Persian literature. This didactic poem, composed of approximately 10,000 couplets, delves into themes of divine love, morality, and Sufi philosophy, marking a significant departure from the courtly and romantic subjects prevalent in Persian poetry of his time.

Sanā'ī's innovative approach laid the groundwork for subsequent Persian poets, notably Farid al-Din Attar and Jalal al-Din Rumi, who drew inspiration from his integration of Sufi mysticism into poetic expression. His works emphasize the transient nature of the material world and advocate for a life devoted to spiritual enlightenment and the pursuit of divine truth.

Sanā'ī's poetry continues to be revered for its depth and spiritual insight, reflecting the rich tapestry of Persian Sufi thought and its enduring legacy in the literary world.
