Adh-Dhahabi and the Taxonomy of Major Sins

Al-Kaba'ir — The Major Sins — is a concise and important work by the great hadith scholar and historian Shams ad-Din Muhammad ibn Ahmad adh-Dhahabi (1274–1348 CE). Adh-Dhahabi was one of the most prolific and authoritative scholars in Islamic history, responsible for the monumental Siyar Alam an-Nubala (biographies of the noble figures), Mizan al-Itidal (a critical dictionary of hadith narrators), and scores of other works in hadith, history, and Islamic sciences. Al-Kaba'ir represents his contribution to the genre of Islamic ethical warning — a concise, evidence-based guide to the sins that the Islamic tradition categorizes as major transgressions against Allah.

The concept of kabira — major sin — is established in the Quran and Sunnah. The Quran commands believers to avoid the kaba'ir (major sins), promising that if they do so, Allah will expiate their minor transgressions. The Prophet, peace be upon him, specifically identified certain acts as among the most serious sins: associating partners with Allah, murder, disrespect to parents, and false testimony, among others. The question of precisely how many major sins there are and what falls into this category has been a topic of scholarly discussion, with answers ranging from seven to several dozen to the view that the category depends on the intention and context of the transgressor.

Adh-Dhahabi's approach in Al-Kaba'ir is to identify a substantial list of major sins and provide, for each, the Quranic verses and prophetic hadiths that establish its gravity. He does not engage in lengthy jurisprudential analysis but presents the primary evidence directly, allowing the severity of each sin to be felt through the weight of divine and prophetic condemnation. The result is a work that functions as a reference for understanding what the Quran and Sunnah specifically warn against with the greatest urgency.

The book's conciseness — it is one of the shorter works of the classical Islamic ethical tradition — makes it accessible to a general Muslim audience rather than only to scholars. Its use in educational settings has been consistent across the centuries, and it has been published in numerous editions and translated into many languages.
