Al-Minhaaj fi Sharh Sahih Muslim ibn al-Hajjaj, also known as Sharh Sahih Muslim, or An-Nawawi's Commentary on Muslim, is a commentary on Sahih Muslim. Its author was Yahya ibn Sharaf An-Nawawi, who explained the hadiths in Sahih Muslim. He took care to clarify the terms, explain their difficulties, and clarify their ambiguities, while also deducing and extracting the rulings. An-Nawawi's commentary on Muslim is considered one of his most famous and beneficial commentaries.

A quote from the introduction to Al-Nawawi’s methodology in explaining the hadith. Mu’alla said in the introduction to his explanation:

“Explanation of Sahih Muslim, may God have mercy on him. I have sought the guidance of God Almighty, the Generous, the Compassionate, in compiling a book whose explanation is moderate between the abbreviated and the detailed, not from the deficient abbreviations, nor from the long and boring ones. Were it not for the weakness of the will, the small number of those who desire it, and the fear that the book would not spread due to the small number of those seeking the long ones, I would have expanded it, and it has reached more than one hundred volumes, without repetition or useless additions. Rather, that is due to the abundance of its benefits and the greatness of its hidden and apparent returns. It is worthy of that, for it is the speech of the most eloquent of creation, eternal prayers. However, I limit myself to moderation and am keen to avoid lengthy ones, and I prefer brevity in many cases.”

Al-Nawawi said in his book: “So I will mention in it, God willing, a number of his brilliant sciences, from the rulings of the fundamentals and branches, manners and ascetic indications, and the clarification of valuables from the fundamentals of the legal rules, and the clarification of the meanings of linguistic terms and the names of men and the definition of the problematic, and the clarification of the names of those with nicknames and the names of the fathers of sons and the ambiguous, and the attention to a subtlety in the condition of some of the narrators and others mentioned at some times, and the extraction of subtleties from the hidden aspects of the science of hadith from the texts and chains of transmission derived, and the definition of a number of similar and different names, and the collection of hadiths that differ on the surface and some who do not investigate the crafts of hadith and jurisprudence and its principles think that they are contradictory, and I will point out what comes to my mind at the moment in hadith of practical issues, and I will point to the evidence in all of that with references except in places where expansion is needed for necessities, and I am keen in all of that on brevity and the clarification of expressions, and when I transmit something from the names of men and the language and the definition of the problematic and rulings and meanings and other transmitted, if it is well-known, then…” “I add it to its speakers because of their large number, except rarely for some good purposes. If it is strange, I add it to its speakers, unless I forget about it in some places due to the length of the speech or because it is one of the things that was explained previously in the previous chapters. If the hadith, name, or word from the language and the like is repeated, I explain what is intended from it in the first place. If I pass by another place, I mention that its explanation and clarification were presented in such-and-such a chapter from the previous chapters. I may limit myself to explaining its precedence without adding, or I repeat the speech about it because of the distance of the first place or the connection of speech or the like or other required interests. I present at the beginning of the book a number of introductions, from which the benefit is great, God willing, and which those seeking investigations need. I arrange that in successive chapters so that it is easier to read and further from boredom.”

Sahih Muslim is the most authentic book of hadith after Sahih al-Bukhari. It is distinguished from Sahih al-Bukhari by its smooth and easy classification. Therefore, it was more widespread among students of knowledge and scholars. Many scholars have commented on it, and the most widely circulated and reliable commentary is that of Imam al-Nawawi, who used the same classification as Muslim but shortened the chains of transmission and some repeated hadiths. Sahih Muslim is the most authentic book of hadith after Sahih al-Bukhari. Al-Nawawi’s commentary on Muslim is considered smoother and more accessible to the student than Fath al-Bari, the commentary on Sahih al-Bukhari by Imam Ibn Hajar al-Asqalani.
