Poem of the Sufi Way, or Nazm al-suluk, is an Arabic poem by the Sufi mystic and scholar, Shayk Umar ibn al-Farid. An exact date of the poem's writing is unknown as Umar ibn al-Farid (1181–1235 ad) is said to have written this text during the course of many years. Widely remarked as Umar ibn al-Farid's most famous work, the poem itself is one of the longest pieces of Sufi literature to date, and is still held in high regard by modern Sufi practitioners. It is 760 verses long. It is often referred to as al-Ta'iyya al-kubra (the Greater Poem Rhyming in T) to differentiate it from a shorter ode that also rhymes in t. The title can also be translated to “the Poem of Progress”.
