1. ‘Abdullah bin ‘Amr said:

“The Prophet صلى الله عليه وسلم said, ‘Reviling one’s parents is one of the major sins.’

They asked, ‘But how could one revile them?’

He said, ‘By reviling a man who in turn reviles the other’s mother and father.’” (Authentic)

Commentary:
The Messenger of Allah صلى الله عليه وسلم ordered not to revile one’s parents by first uttering a stirring statement that invites the attention of the listener and showed the weight of the matter. Although it is against man’s innate disposition to revile his parents, his insult of another person’s parent could lead to that. As such, the hadeeth is evidence that a thing becomes forbidden if it basically leads to something forbidden.

2. ‘Abdullah bin ‘Amr bin al-‘As said:

“That a man should provoke someone to revile his parents is one of the major sins in the sight of Allah the Mighty.” (Good chain)

Commentary:
The statement takes a cue from that of Allah’s Messenger صلى الله عليه وسلم in the hadeeth that just preceded.
