Methodology, Standards, and Controversy

Al-Mustadrak is one of the most discussed and debated works in the hadith sciences, primarily because later scholars found that al-Hakim's claims about meeting the standards of Bukhari and Muslim were often overstated. Understanding the controversy requires understanding both what al-Hakim was trying to do and where his methodology fell short.

Al-Hakim's stated criterion was that a hadith met the standard of Bukhari or Muslim if it was transmitted through narrators whom those scholars had accepted in their Sahih collections. This criterion — called the shart al-Bukhari or shart Muslim (al-Bukhari's condition or Muslim's condition) — is theoretically sound: if Bukhari accepted narrator X in his Sahih and narrator Y in his Sahih, then a chain consisting entirely of such accepted narrators should arguably meet his standard.

The problem, as later critics identified, is that Bukhari and Muslim did not accept narrators uniformly across all their transmissions. Accepting a narrator in one chain does not mean accepting every hadith that narrator transmitted in every chain. A narrator might be reliable in general but have specific weaknesses in transmission from certain teachers or in certain categories of hadith. Al-Hakim's somewhat mechanical application of the criterion did not account for these nuances.

Adh-Dhahabi's Talkhis al-Mustadrak, printed alongside the Mustadrak, explicitly identifies hadiths in al-Hakim's collection that adh-Dhahabi considered weak or even fabricated. Adh-Dhahabi found numerous cases where al-Hakim had accepted narrators who were actually criticized or where the chain had hidden defects that al-Hakim overlooked. These identifications are valuable because they alert the reader to hadiths requiring additional scrutiny.

The scholarly consensus on al-Mustadrak is nuanced: the collection contains a core of genuinely strong hadiths that are valuable supplements to the canonical collections, alongside a significant number of hadiths that do not meet the standard al-Hakim claimed for them. Later researchers including al-Albani have re-evaluated many of the collection's narrations with updated methodology, producing more systematic assessments. Using the Mustadrak requires knowing this background and consulting adh-Dhahabi's Talkhis alongside the original.
