Mohammed Bin Salman, the crown prince of Saudi Arabia in a new interview on Al Arabiya describes what he sees as the problem with a majority of hadith which he says are not reliable for not having good chains and should not be used in Sharia anymore.
The de facto ruler of Saudi Arabia said only few hadith have detailed chains of many/groups of narrators, these are the Mutawatir hadith and will be used along side the Quran in jurisprudence.
Another number “Ahad” hadith have a single person in the chain, and need to be checked for compatibility with Quran before use.
The majority which the crown prince says he cannot use for Shariah law have longer single narrator chains with unknown persons or breaks in the chains. These are the Khabar hadith and are most of the hadith, he said.
On Wahhabism, MBS said the Ibn Wahab himself would reject the continuous use of his interpretations, expatiating that the Quran transcends time and is open to continuous interpretation. Saying that no one now or in the past is infallible.
Much of this controversial discussion is viewed in this clip with English subtitles which is taken from the end part of the interview.
