What is clear from the plethora of research presented is that opinions on the subject of the Muqaṭṭa’āt, both contemporary and traditional, are divergent and in some cases conflicting.
Traditional Muslim scholarship, partly due to the reverence with which the Qur’ānic corpus is held, has steered clear of investigating the phenomenon too profoundly for fear of the accusation of heresy or textual blasphemy. We need only note the circumstances surrounding Dr Rashad Khalifa’s demise to gain an understanding of the risks involved in questioning the textual apparatus of the Holy Book of Islām. That said, several plausible explanations for the presence of the Muqaṭṭa’āt have been offered by the traditional scholars, notably Ibn Kathīr, as-Suyūtī and, more recently, aṭ-Ṭabāṭabā’i. Most traditional scholarship has envisaged the letters as integral to the original revelation, and explanations have centred around their relevance in communicating the text’s miraculous qualities or its divine origins.
In terms of contemporary erudition, academics have tended to fall under two classifications: those who see the Muqaṭṭa’āt as part of the original revelation, and those who believe that the letters were part of the redaction process and/or became integral to the existing text erroneously. Nevertheless, the rational approach to this textual phenomenon has unearthed some interesting and very plausible explanations for the occurrence of the letters.
The implications for inter-religious dialogue of the Muqaṭṭa’āt are twofold: firstly, it behoves the Christian interlocutor to acknowledge that Muslims consider the letters to be God’s speech, preserved for eternity in the Divine Tablet (al-Lawḥ al-Maḥfūẓ): a form of theophany. Moreover, as the majority of Muslims today endorse the creedal doctrine of the uncreatedness and inimitability of the Qur’ān, any serious textual discussion would have to recognise that any criticism of the text amounts to a direct attack on the authenticity of the religion as a whole.
Secondly, unlike Christianity but paralleling Judaism, Islām holds a special place within tradition for the inlibration of the revelation and the ritual recital of the text. The Muqaṭṭa’āt form part of the daily ritual of any Muslim and any discussion of their origin and import should appreciate their importance in Muslim orthopraxy.
This expository paper has included a comprehensive review of current research on the textual apparatus known as the Muqaṭṭa’āt. Recommended areas for further investigation would be recent investigations into the potential links between the letters and Egyptian hieroglyphs. Several books have been authored on this topic recently, but it is beyond the author to comprehend and review texts of such complexity in the Arabic language at this time. Another feasible area of research might be a comprehensive review and comparison of apocryphal codices to ascertain any non-concordance with the ‘Uthmānic codex in terms of the letters.
