'However in another aspect in my view, being "Qur'an-centric" is a part of what I see as the "Arabization of Islam".'
I ask, avoiding the terms, 'Qur'an-centric', etc:
Naturally, a person who believes in Qur'an will want to study it.
And, it is in the Arabic language. Inevitably, he has to delve into the nuances of the language, at least with respect to the Qur'an, in order to understand it.
In order to enjoy Shakespeare, we have to be well versed in the English of Shakespeare's times.
Of course, Qur'an is more than that.
Therefore, in my view, it is only that the Study of the Qur'an should not lead us to adopt any prejudices regarding languages. Qur'an itself makes this matter clear.
And, the Qur'an guides us to what is most firm and most consistent. (17:9)
Most firmly and consistently, it gives glad tidings to those who believe and do good deeds. (17:9)
Most firmly and consistently, it announces, that God has prepared for those who believe not in the Hereafter, a grievous chastisement. (17:10)
This is the same theme as in (2:62, 5:69), yet, with a special emphasis regarding the belief in the Hereafter.
No prejudice arises from the diligent and constant study and recitation of the Qur'an.
Every kind of prejudice is attributable to the step motherly treatment given to the Qur'an, as by the 'orthodox' Muslims.
The real scholars of the Divine Book, irrespective of which language it was revealed in, are not at all arrogant and prejudiced (5:82).
