Are all of the hadiths in Sahih al-Bukhari and Muslim authentic, or are there weak hadiths among them?

Scholars have agreed that the two Sahih collections (Bukhari and Muslim) are the soundest books after the Quran, and that Bukhari is sounder than Muslim in terms of hadith methodology. Muslims have received both Sahih collections with acceptance, and it is not permissible to doubt them or raise suspicions about their hadith, as this would undermine their credibility and shake established principles. What the two Shaykhs (Bukhari and Muslim) agreed upon is undoubtedly authentic. As for what one of them narrated exclusively, its authenticity is certain due to the Ummah's acceptance of it, with the exception of a few minor points that some Huffaz (hadith masters) have discussed, which are known to specialists. Some scholars have criticized a number of hadith in Sahih Muslim, and very few in Sahih Bukhari. Al-Albani's weakening of hadith in the two Sahih collections is not accepted unless he was preceded in it by an early, independent Mujtahid Imam.
