Quran 24:11-25 Specifics About The Incident
The allusion sufficed then because the people were there and they knew exactly what it was alluding to. For us we have to use ahadith to understand what was going on because of course we’re not there when it’s being revealed. And where do we know it was against Aisha رضي الله عنها except from ahadith?
But the Quran was revealed to a certain people to talk about the situations they were facing which is made clear when specific situations like badr are mentioned. So to get the real message we should have to immerse ourself in what occurred in those times and that’s only from ahadith
