The expression “the verse was revealed concerning such-and-such” does not always settle a unique date or incident of revelation. Early scholars sometimes used it to identify a fitting application of the general verse.
One exegete might name an individual and another a community; both may be explaining the scope of the wording, not proposing competing historical occasions.
Research method: assess the whole report, its manner of presentation, and the verse’s general language before separating an actual occasion of revelation from an illustrative application.
