The central lesson is that legal consequences cannot be inferred from words without examining their conventional assignment, current usage, and contextual indicators.
Haqiqah is the assigned meaning; majaz is a transferred related meaning. The chapter states a particular restriction on combining the two in a single occurrence. An impossible literal sense cannot operate; an abandoned literal sense has yielded to customary usage; a living literal sense may compete with an established figurative sense, producing distinct juristic priorities.
The sale, bequest, oath, residence, litigation, and manumission cases show that semantic distinctions affect legal outcomes. The next chapter turns to the methods and justification of metaphorical transfer (istiĘżarah).
