The Literary Challenge (I‘jaz) and Its Unfalsifiability

Islam’s premier evidential miracle is the Quran itself: the doctrine of i‘jaz holds the book to be literarily inimitable, and the Quran stakes its origin on a challenge (tahaddi) — produce ten surahs like it (11:13), or a single surah (2:23; 10:38), “and you will not” (2:24). The critique is fourfold. First, the challenge is unfalsifiable in practice: the criterion of “likeness” is undefined and adjudicated by Muslim scholars who begin from the premise that no rival can succeed, so every attempt is declared a failure by definition. Second, the standard is subjective: literary excellence is not a measurable property, and aesthetic judgments vary by language, era, and taste — billions who do not read classical Arabic cannot assess it at all, which is a strange feature for a universal proof. Third, rivals were in fact composed (the verses attributed to Musaylima; later pastiches) and simply ruled inadmissible. Fourth, the doctrine is historically late: i‘jaz became a developed science only in the ninth–eleventh centuries (al-Jurjani’s Dala’il al-I‘jaz, d. 1078), two to four centuries after the Quran, which is when the apologetic need arose — not a sign of an evidence self-evident from the start.
