What does the claim mean here?
Within the limits of the available summary, the point is that the association of polytheism with “الظلم العظيم” (“the great injustice”) is not presented as a passing error, but is understood in terms of the continuation of a mistaken decision. This is a preliminary reading pending verification of the episode.
What is attributed to Shahrur
The available evidence provides this characterization: Shahrur links polytheism with the great injustice and understands the connection from the perspective of an ongoing mistaken decision. The evidence is an editorial paraphrase, not a verbatim statement from him.
Atlas explanation
The page preserves the distinction between what the summary reports and any additional explanation: it does not establish here a detailed definition of polytheism, nor does it specify the elements of the “القرار الخاطئ” (“mistaken decision”). The explanation is therefore limited to noting that the connection is recorded in the episode source in a form requiring review.
Conclusion
In a limited synthetic sense, the statement can be read as moving from naming polytheism to assessing it as injustice; however, the available evidence does not establish how this transition is constructed or its scope, so this detail is not attributed to Shahrur.
Open question and documentation limits
Did Shahrur use the very phrase “قرار خاطئ مستمر” (“ongoing mistaken decision”) in the episode, or is it an editor’s summary? And what exactly is meant by the decision in the episode’s context? The available material does not answer this, because the quotation field and raw context are empty, and the evidence status is “غير مؤكد من المصدر الأصلي” (“unconfirmed from the original source”). See Episode 25, while retaining the existing book links: Toward New Foundations for Islamic Jurisprudence and The Mother Book and Its Elaboration.
