أن النص إذا قُرِئَ بقراءتين أو رُوِيَ بروايتين كان العمل به على وجه يكون عملاً بالوجهين أولى
If a text has two established readings or reports, prefer a workable interpretation that gives effect to both when possible.
Harmonization means assigning each established wording an appropriate application rather than prematurely treating them as contradictory. It requires genuine textual support and an interpretation that can actually operate in law.
An unverified alternative reading cannot be treated as an established recitation merely to manufacture a new rule.
