The Book of the Forty An-Nawawi (The Forty in the Principles of Islam and the Rules of Rulings)
By Imam Muhyiddin Abi Zakaria Yahya bin Sharaf al-Nawawi (d. 676 AH)
It included forty-two hadiths, selected by Imam al-Nawawi to cover different sections and various topics. He said about him (and each hadith is a great rule of the religion, and scholars have described it as the focus of Islam on it, or it is half of Islam, or a third of it, or something like that.
Features of this application:
1. Care should be taken to control the wording of the hadiths according to the approved versions.
2. Commitment to Imam al-Nawawi’s explanation of the terms of the hadith, along with an explanation of some other terms that we thought would be useful to explain.
3. Give a title for each hadith in a way that makes it easier to understand its content.
4. Recording conversations audio to facilitate their memorization and mastery.
5. Preparing an overview of the life of each narrator and recording it audio.
6. Creating some explanatory tables that help young people memorize and review hadiths.
7. Developing two proposed plans to preserve the nuclear forty and reviewing them, one intensive and the other non-intensive.
