Seeking a ruling from the Quran requires more than finding an explicit mention of a case’s name. A rule can be communicated by direct wording, indication, or another recognized form of textual implication.
A general expression may cover numerous cases; a separate text might specify or qualify its scope. This is why the earlier discussions of general versus particular terms, unrestricted versus restricted wording, and modes of textual indication matter in legal derivation.
Principle: A rule supported by sound Quranic indication is not abandoned merely because an independent analogy suggests a different outcome.
