al-Khiṣāl is a unique work in the realm of Shīʿī Ḥadīths. Authored by Shaykh al-Ṣadūq, the book focuses on exploring traditions by categorising them on the basis of the numbers mentioned in the traditions, which is similar to what can be found in the book al-Maḥāsin for al-Barqī. Each section of the book is dedicated to a specific number, starting from one and extending up to one million. In the course of gathering these Ḥadīths, one will find traditions dealing with history, doctrine, ethics, jurisprudence and a large variety of genres.
