«مَا فِيهِمْ إِلَّا مَنْ يُحْفَظُ عَنْهُ وَلَا يُتَحَفَّظُ مِنْهُ»
Every person there offered words worth preserving and posed no need for wariness.
The same root ḥ-f-ẓ produces two related ideas: words worth remembering from these companions, and no need to guard oneself against them. The narrator assesses the current gathering.
That favourable description does not automatically cover a stranger who later knocks at the door. Literary interpretation must preserve the scope of the narrator’s judgement.
Applied question
