What Is Meant Here?
What is meant is that necessity, under the available formulation, does not turn the exception into a general rule or make the permissibility of what is forbidden a means of expanding rulings.
What Is Attributed to Shahrur
The available paraphrase from Episode 18 describes the permissibility of what is forbidden in cases of necessity as addressing a very rare situation, not as an ordinary mechanism for producing new rulings. This attribution is provisional because the evidence itself requires review and does not include a verbatim quotation from the episode.
Atlas Explanation
The scope of the claim can be set at its minimum: it concerns the function of necessity in this formulation and does not itself provide a list of prohibited matters or detailed rules for applying the exception.
Conclusion
If the attribution is confirmed after referring back to the episode, it prevents reading necessity as an ordinary avenue for generating new rulings. This is a composite inference from describing the situation as rare and denying that it is an ordinary mechanism, not an independent quotation.
Open Question and Limits
The available content does not explain how necessity is determined in particular cases, nor does it provide a documented example from the episode. It is necessary to refer back to الحلقة 18 to verify the wording and context, then examine its connection to what may appear in Toward New Foundations for Islamic Jurisprudence and Religion and Authority without assuming that these connections establish the claim in themselves.
