The Arbaʿin or Chihil Kalima of Jamiʾ is a choice collection of Traditions of the Blessed Prophet ﷺ. The main emphasis is on cultivating high qualities of character. The compiler, who was a great Persian scholar and poet, further enriched his beautiful hadith selection with pithy and eloquent paraphrases in verse. In this edition, Turath Publishing presents the original Arabic and Persian texts together with the English translations of both. These are complemented by an introductory account of Jamiʾ and his works, and also by notes on both the content and the sources of the hadiths. Born near Kharjird in western Afghanistan, ʿAbd al-Rahmān Jāmīʾ (d. 896/1492) was already a religious scholar of tremendous ability when he experienced a call to the mystical Path. Settling in the Timurid capital of Herat, Jami embarked on a spiritual and intellectual journey that led him to produce some of the greatest didactic and lyric verse in the canon of classical Persian poetry, as well as prose works on a remarkably wide range of subjects, including metaphysics, ethics, jurisprudence, biography, and Arabic grammar.
