The Book Of Major Sins By Muhammad ibn Sulayman at-Tamimi

Allah has made sins a cause of harm — harm to the heart, to the body, to rizq, to relationships, and ultimately to the standing of a person in the akhirah. The Prophet (peace and blessings be upon him) said: "Every son of Adam sins, and the best of those who sin are those who repent." But repentance requires that a person first recognize what constitutes a sin — and particularly what rises to the level of a major sin (kabeerah), which carries its own severe warning in the Qur'an and Sunnah.

The Book of Major Sins by Muhammad ibn Sulayman at-Tamimi presents a clear, evidenced account of the major sins — what they are, what the Qur'an and Sunnah say about each, and what consequences they carry — so that the Muslim knows what to guard themselves against with full awareness.

What This Book Covers

Defining the Major Sins

The book opens by addressing what makes a sin "major" — the scholarly discussion around this question, the indicators found in the Qur'an and Sunnah (explicit warning of Hellfire, curse, or severe punishment), and why distinguishing major from minor sins matters practically for the Muslim's spiritual life and acts of worship.

The Major Sins Enumerated and Explained

Each major sin is presented with its Qur'anic and hadith evidence, an explanation of what it entails, and — where applicable — the conditions under which it applies. The treatment is grounded in transmitted texts rather than human reasoning, giving the reader confidence that what is presented reflects the actual position of the Shari'ah.

The Path of Repentance

The book does not leave the reader in despair. Allah's mercy is vast, and the door of tawbah is open. The conditions of a valid repentance are addressed, and the Muslim is given both the warning they need and the hope that is equally part of the religion.

About the Author

Published by International Islamic Publishing House (IIPH), this work draws on the classical Islamic tradition of scholars who catalogued major sins as a service to the Muslim community — helping people recognize what to avoid and what to repent from.

Who This Book Is For

Every Muslim who wants to know what the major sins are by name and evidence — not by cultural assumption or vague warning. Essential for those seeking to purify their lives of what Allah has explicitly warned against, for those who have fallen into sin and want to understand the path of return, and for students of fiqh and aqeedah who want a clear reference on this topic.
