Our objective has always been to produce an English-language comprehensive, but yet compact, book of hadith that is easy to read and understand by Muslims and non-Muslims alike. Simply put, there is no one book of hadith that meets that criterion better than the book written by Imam Al-Nawawi in the thirteenth century and known as Al-Nawawi Forty Hadiths and Commentary. The book covers all aspects of Islam from the very basic abstract definitions to the most practical daily chores. It contains all the major sharia laws. It is taught to all Muslim students around the world. The book is a horse's mouth for hadith commentary and is the cream of the crop of all hadith books. We translated from Arabic Imam Al-Nawawi's book in its entirety including the lines of poetry. This English translation by the Arabic Virtual Translation Center is complete, accurate, unfiltered, and unbiased.
