The research explores the morphosyntactic variations and scribal practices in the Old Kanembu manuscripts with a focus on identifying and bringing out the codes used by Borno Ulamau in disseminating the exegesis (Tafsīr) of the Qurān in Old Kanembu (henceforth, OKb) and its modern variant into the linguistic spotlight for language documentation. OKb is one of the oldest Saharan languages that has been reduced in writing Ajami script since the early development and expansion of Islam into the Kanem-Bornu Empire between the 12th and the 16th centuries. OKb is the language whose footprint can only be traced to the ancient Qurānic manuscripts of old Borno. A modern-day variant of OKb, known as Tarjumo, is still in use by the modern-day Borno ulamāu in describing, interpreting, and analyzing written Arabic texts in the Kanuri society and the Kanembu/Kanuri community in the diaspora. OKb is used as the language of the Qurānic commentary and Tarjumo is the hybrid of OKb, modern Kanembu, and Kanuri used in both oral and written forms. In this work, we examined, identified, and analysed a selected part of the Qurān chapter 79 Sūrat- An-Nāziʿāt Those who pull out.
