Professor Nasser, Associate Professor of Near Eastern Languages and Civilizations teaches Arabic literature and Islamic Civilizations courses. His previous posting was as a University Lecturer in Classical Arabic studies at the University of Cambridge (UK), in the Faculty of Asian and Middle Eastern Studies.
Nasser put together the EvQ site (with colleagues and PhD students I would no doubt believe) to list the variants that are found across the different versions of the Quran.
EvQ: Encyclopedia of the [variant] readings of the Qur’an is an open access platform designed to study the reception and transmission history of the Qurʾān. The platform functions as a critical apparatus of the Qur’an; it provides data on the variant readings recorded in the Arabic sources. EvQ was developed thanks to funds and awards through Harvard University.
The relevant part of this work is that Muslims are taught by their leaders that the Quran has been perfectly preserved from the begining by Allah. The claim is that the Quran that Muhammad received is the very same one that we have today and that everyone in the world has the same version. Some even claim that the version today is identical even to the dot (diacritic marks for defining not just vowels but also defining consonants) but that would be impossible because their use did not start to occur until intil the next century. All the earliest manuscripts have no dot or markings within them. Scratch beneath the surface of this claim of perfect presevation and we see a much different story. We know today that there are over 30 different versions of the Quran and within them much variance is found. What Dr Shady has tried to do is record all of these as an academic study tool for all to use.
The EvQ website tool can be found here.
Needless to say Dr Nasser has had much push back and criticisms from some in the Islamic community, but he has pressed on regardless with his research
Below are two videos. One on Dr Nasser's discussion with Gabriel Reynolds on his Youtube channel, Exploring the Quran and the Bible,and another of Nasser teaching at another University.
