Sahih Muslim

How Muslim grades — and why the numbers disagree

مُسْلِمُ بْنُ الْحَجَّاجِ النَّيْسَابُورِي

206–261 AH

Muslim does not stamp Sahih on each report. The book is the grade. What looks like many hadiths is often one wording on several roads — and each edition counts those roads differently.

International / sequential

1–7563 here. Every isnad is a number — including “the same hadith through another chain.”

Arabic / Abdul-Baqi

About 3,033 matns. Variant roads are dotted: 8.01, 8.02… The number people usually mean by “Muslim 8.”

In-book

Book and hadith inside the kitab: Faith 1:1 is Jibril’s first road, not sequential 1.

Two doors, one grade-word

Bukhari and Muslim both kept only sahih. They do not use the same key for the lock.

  • Bukhari — proof of meeting

    He wanted evidence that A had sat with B, not only that they lived at the same time. That extra door is liqa.

  • Muslim — contemporaneity

    If two thiqah men shared an era and tadlis is not feared, Muslim accepts the link (muasarah). He then lays every other road beside it.

  • The introduction is method

    Sequential 1–92 sit in book 0 — the Muqaddimah. They teach why the isnad is religion. They are not the first hadiths of Kitab al-Iman.

  • Later stamps

    Al-Albani, Shaib al-Arnaut and others grade the Sunan by name. On Muslim the API is empty because the compiler already closed the file.

Who is allowed to grade

  • The compiler

    Bukhari and Muslim grade by inclusion. A report in the Sahih already passed their door. A blank grade is not a missing test.

  • The teacher-collector

    Tirmidhi names sahih, hasan, gharib on the page. Abu Dawud often flags a wound, or is silent on purpose.

  • The later critic

    Albani, Arnaut, Ahmad Shakir, Muhammad Fuad Abd al-Baqi, Zubair Ali Zai. They re-walk old files. They can disagree — that disagreement is the method working.

  • The reader

    A grade is about attribution to him ﷺ, not about whether the sentence is wise. For fiqh, ask a qualified scholar.
