A ruling’s operative application may cease when the cause underlying it no longer exists.
The historical juristic discussions of those whose hearts were to be reconciled and the share attributed to the Prophet’s relatives illustrate an important difference: a situation-specific entitlement may cease to apply when its operative rationale is absent. This is not the same statement as claiming that a Quranic text itself has been repealed.
The examples belong to the Hanafi legal-theory discussion. Other jurists may differ on the relevant legal details and applications.
