Wait till he finds out the transmission of the Quran is a "1400 yr long chain of person A claiming that B told him that C told him that D told him that E told him that F told him that God spoke to the Prophet in a cave"
I am not Quranist but Isnad hadith seem off to me because it is just 200 yr long chain of person A claiming that B told him that C told him that D told him that E told him that F told him that PBUH ate chicken or something. How do we know that none of them faked their narration??
