A Companion might ask the Prophet ﷺ a question, or a particular incident might arise in his lifetime. Guidance would then be drawn from a verse, and a later report might describe the verse as “revealed concerning” the issue.
That sequence alone does not prove that the question caused the verse to be revealed for the first time. The verse may already have existed and supplied the answer, or its bearing may have been explained in that meeting.
The crucial enquiry is whether the report explicitly records a revelation at that moment, or merely records the use of a verse to explain the ruling. These are distinct historical assertions.
