Abū Ḥafṣ Nasafī’s “Kitāb Al-Qand” is an Important Historical Source

This article discusses Abū Ḥafṣ Nasafī’s “Kitāb Al-Qand” as an important historical source. Serious shortcomings and deficiencies in this publication have made it urgent to prepare a scientific-critical text of the “Kitāb al-Qand” in the future. This was because it was possible to compare the biographies contained in the Paris manuscript (“‘ayn” chapter) and to correct a number of errors in the Istanbul manuscript and to include them in the critical text.
