Forty hadith consisting of only two words from the responses of the Prophet Muhammad. This book was not compiled from the book of Imam An-Nawawi's "Forty Hadith" but, Shaykh Mustafa Mabram researched and found forty different hadiths from the responses of the Prophet to the companions in matters of the religion. The book is very easy for the student of knowledge to memorize and utilize in knowledge. The book is special as it shows the wisdom of using shorts words or phrases but very powerful in meanings.
