والله تعالى أعلم بالصواب
God knows best what is correct.
Deriving legal rulings requires more than reading the surface of a single verse or report: verbal indications, the strength of evidence, consensus, causal analysis, analogy, and the limits of proof interact.
Conclusion: A legal inference should claim no more than its sound premises establish. Absence of a cause negates a ruling only where the cause is exclusive. Istishab can defend an existing state but does not automatically establish a new entitlement.
The final principle is to identify the reach of each proof, examine the cause, and distinguish protection of an established status from creation of a fresh claim.
