The Kitab Sirr al-Asrar is commonly attributed to Aristotle, but its actual authorship is shrouded in mystery. Scholars believe that the text was written in the 9th or 10th century CE, during the Islamic Golden Age, when Greek philosophical ideas were being translated and assimilated into Islamic thought. The text is thought to have been written by a Muslim author who was influenced by Aristotelian philosophy, Sufism, and Islamic theology.
