This book by Imam An-Nawawi is one of the books that have been widely distributed and enjoyed great popularity among Muslims.

This book contains forty-two Hadiths, Imam AnNawawî has gathered in it the important points of the religion touching on both the fundamental principles -al-usûl- and the practical applications -al-furû'-, he said about his pamphlet: "Each Hadith that it contains is a fundamental rule of the religion, some scholars have described these Hadiths as being the turning point of Islam, some have said that they represent half of the religion, others a third of the religion, as well as other qualifiers of this kind."

It is truly a blessed book, for which Allah has decreed popularity and expansion.
