Tatabbu' 209 (and others)
Qatada — prone to tadlis (concealing sources in isnad)
Hadith Text
This is a Tatabbu' entry -- a cross-collection scholarly follow-up.
Tatabbu' (literally "the follow-up") is the short name for Kitab al-Ilzamat wa al-Tatabbu', a 10th-century work by the hadith scholar al-Daraqutni reviewing specific narrations in Sahih al-Bukhari and Sahih Muslim. The number in the reference points to that catalog's entry -- not a hadith number on this site -- so a direct hadith link is not always available.
Scholarly Critique
Qatada widely accepted by Bukhari, Muslim and majority; tadlis accusation from a minority view. One of only three transmitters al-Daraqutni criticizes in both Sahihs.
