forgotten by Muhammad,
For Q 2.106 at least a dozen suggested reading have been recorded --
ample evidence of the extent, and hence of the significance, of the
dispute as to the meaning. What was eventually settled as the joint
exegesis of Q 87 and Q2 (the interpretation of each of these verses
operating upon that of the other) was that there was indeed verses
once revealed to Muhammad as part of the 'total Qur'an revelation'
which, however, have been omitted from the collected texts of the
Qur'an, the mushaf. That had by no means occurred from Muhammad's
having merely forgotten them. Q 87 refers to God's will and Q 2 uses
the root n.s.y. in the causative. God had caused Muhammad to forget
in conformity with the mysterious divine intention as to the final
contents of the Book of God.

He instances the report from Abu Musa as to the sura like Bara'a
which was revealed, but later withdrawn. Abu Musa recalled
something of it, but Mekki resolutely refuses to go into further
detail. The Qur'an text cannot be established on the basis of
reports. The many examples of this category he would therefore
prefer to pass over in silence. God alone knows the truth of the
matter.
(John Burton, The Collection of the Qur'an, 1977, p. 85, Mekki, "bab aqsam al naskh")
The extreme Sh`ia, the Rafidis, alleged that the impious rulers
had expunged from the mushaf some 500 verses including those which
most unambiguously marked out `Ali as the appointed successor to
the Prophet.... The rebels against `Uthman, justifying their revolt,
enumerated amongst their grievances their resentment at his 'having
expunged the mushafs.'
