Is there some mention in narrations that disobedience to parents being among the most major of sins?
Yes, this has been authentically reported in Sahih Bukhari and Sahih Muslim.
Sayyiduna Abu Bakrah (radiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alayhi wa sallam) asked, “Should I not inform you of the most major sins?’ The Sahabah (radiyallahu ‘anhum) replied, ‘Most certainly O Rasulullah.’ Nabi (sallallahu ‘alayhi wa sallam) said: ‘Ascribing partners to Allah and disobedience to parents…'”
Some versions suggest that Nabi (sallallahu ‘alayhi wa sallam) repeated the question thrice.
(Sahih Bukhari, Hadith: 2654, 5976, 6273, 6919 and Sahih Muslim, Hadith: 87)
And Allah Ta’ala Knows best.
