Imagine you have a book that tells you everything your parents want you to know about how to live a good life. Sahih Muslim is like that book but for grown-ups who are Muslim.
It is a book that contains sayings and teachings of the Prophet Muhammad, who was a holy person and a messenger of Allah (God). These sayings and teachings are called Hadith.
Sahih Muslim is a collection of Hadith that are considered authentic and reliable by Muslims all around the world. It was compiled by a man named Imam Muslim who lived a long time ago.
In this book, you can learn about different things like how to pray, how to be a good person, how to treat others with kindness, and how to live a life that is pleasing to Allah.
Muslims read Sahih Muslim to learn from the wisdom of the Prophet Muhammad and to try to live their lives according to his teachings.
