This is how Al-Khwarizmī said

This book examines and compares very important Islamic manuscripts from the Middle Ages. It is considered the first study of its kind in the history of scientific research, especially since these manuscripts deal with precise mathematical sciences such as mathematics and astronomy, yet intersect with the philosophy of Islamic Sufism.This book examines the above-mentioned manuscripts in terms of their content orientation, as well as the scientific ideas underlying the philosopher's theory. It then compares this scientific content with a specific philosophical theme through which the philosopher sought to highlight his position on a Sufi, cosmogonic, scientific conception of the creation of the world. The book examines pivotal manuscripts in the history of human sciences, in which we also discern a Sufi intellectual aspect, such as the manuscript of the Zij al-Sindhind by al-Khwarizmi.
