In his seminal work, I'jaz al-Qur'an, the renowned Ash'ari theologian Abu Bakr al-Baqillani presents a rigorous defense of the Qur'an's divine inimitability. He meticulously analyzes the linguistic and rhetorical brilliance of the sacred text, arguing that its unique style and eloquence are beyond human capacity to replicate. Through detailed comparisons with pre-Islamic poetry and prose, al-Baqillani establishes the Qur'an's status as a standing miracle, solidifying a central doctrine of Islamic belief. This classic text remains a cornerstone of Qur'anic studies and Islamic literary criticism, profoundly influential for centuries.
