These most ancient and basic works on Islam do not reveal any
mention of Tahreef-Makani, or any addition to or subtraction
from the present version of the Holy Qur'an which is in our
hands. The only mention found in these basic authorities
concerns Taweel (interpretation). In the Tenth Volume of the
Biharul-Awar of Mullah Baqir Mujlisi, there is a discussion
between Abdullah ibne Abbas and Ma'aviah. Ibne Abbas, in
answering Amir Sham, who had commanded that praising Ali
and the Ahlul-Bait be discontinued, does not speak of any
distortion or misarrangement of the verses of the Holy Qur'an, or
of any addition or subtraction, but he questions Ma'aviah,
challenging him on the interpretation of the verses of the Qur'an
which expressly speak of Ali and the Ahlul-Bait. This is another
clear evidence that the present Qur'an is the same collection as
was made in the lifetime of the Holy Prophet at his command,
and was the collection that was with Ameerul-Mo'mineen Ali
ibne Abi Taleb, with the special explanatory notes from the Holy
Prophet and by himself regarding the external as well as the
internal meaning of the Word of God.
