Quranism describes any form of Islam that accepts the Quran as revelation but rejects the religious authority, and/or authenticity of, the Hadith collections. -- Wikipedia
Frequently, non-Quranists use ahadith to better understand the Qur'an. Likewise, they use tafsir to better understand the Qur'an.
A Quranic tafsir will often explain content and provide places and times, not contained in Quranic verses, as well as give the different views and opinions of scholars on the verse. -- Wikipedia
This motivates my question:
Question: Do Quranists also reject tafsir?
The Wikipedia page for Quranism also writes:
Ahle Quran scholars may use Tafsir when pursuing the interpretations of the Quran.
While an unreferenced snippet, this suggests it's possible that different Quranists have different attitudes towards tafsir. The Wikipedia page for tafsir
currently also writes used to write:
Wahid Al-Qur'an, or "The Qur'an Alone" (a.k.a. Quranism [قرآنيون Qurʾāniyūn]) is the school of tafsir first used by Muslims during the first two centuries of Islamic history[Source needed].
This indicates that Quranists have a different kind of relationship with tafsir.
