Book of Major Sins, The

The Book of Major Sins by Imam Muhammad ibn Sulayman At-Tamimi does one specific, useful thing: it lists roughly seventy major sins in Islam, each backed by its evidence from the Qur’an and authentic hadith, without padding or extended commentary.

Why a List Rather Than a Treatise

Islam does not treat man as expected to be perfect — fallibility is part of being a limited, created being. What Islam does hold a person accountable for is failing to seek the means of improvement that are actually available to him. Knowing precisely what counts as a major sin, rather than a general sense of right and wrong, is one of those means, and At-Tamimi’s book supplies it directly: sin by sin, evidence by evidence.

Who This Book Is For

Anyone who wants a clear, sourced reference for what Islam classifies as a major sin, useful for self-accountability, for khutbahs, and as a starting point before a longer commentary on the same theme.
