Is it true that Bukhari narrated from some of the people of Bidʻah (innovation)?

Al-Bukhari and Muslim narrated from some people of innovation (Ahl al-Bid'ah) according to specific criteria, the most important of which are: that their innovation is not considered disbelief (kufr), and most of them were not callers to their innovation. Narrations from them are usually accepted as supporting evidence (mutaba'at) and corroborations (shawahid). Their narrations are accepted as primary sources (usul) if there is a corroborator for them, in addition to their truthful speech and mastery of memorization, and if the innovator narrates something that no one else has. Al-Khatib al-Baghdadi reported that scholars recorded their narrations and used their reports as evidence, which became like a consensus. The Shi'ism narrated from its adherents differs from pure Rafd (rejectionism). A Shi'i, in the understanding of the Salaf, is one who preferred Ali over Uthman, or believed that Ali was correct in his wars, while still giving precedence to and preferring the two Shaykhs (Abu Bakr and Umar), and being pious, religious, truthful, diligent, and not a caller to his innovation. As for Rafd, its narration is rejected.
