Shaykh al-Islam Ahmad ibn Taymiyyah, may Allah have mercy on him, is considered one of the best and most beautiful books on the doctrine of Ahl al-Sunnah wa al-Jama'ah, so scholars and students of the work were keen to explain it and benefit from it, including the commentary of Sheikh Saleh al-Fawzan.

The Book of Faith is a collection of four letters from the relics of our righteous predecessors and our modern imams, presented in a simple and smooth style while avoiding excessive length, and this book has won the admiration of many.
