Some Verses Missing

According to Professor Guillaume in his book, Islam, (pp. 191ff.), some of the original verses of the Quran were lost.

For example, one Sura originally had 200 verses in the days of Ayesha. But by the time Uthman standardized the text of the Quran, it had only 73 verses! A total of 127 verses had been lost, and they have never been recovered.

The Shiite Muslims claim that Uthman left out 25 percent of the original verses in the Quran for political reasons (McClintock and Strong, Cyclopedia, V:152).

That there are verses which got left out of Uthman's version of the Quran is universally recognized (Shorter Encyclopedia off Islam, pp. 278-282; Guillaume, Islam, p. 191; Wherry, A Comprehensive Commentary on the Quran, pp. 110-111).

John Burton's book, The Collection of the Quran, which was published by Cambridge University, documents how such verses were lost (London University Press, 1977, pp. 117ff. See also Arthur Jeffery, Islam: Muhammad and His Religion, New York; Liberal Arts Press, 1958, pp. 66-68).
Burton states concerning the Muslim claim that the Quran is perfect:

"The Muslin accounts of the history of the Quran texts are a mass of confusion, contradiction and inconsistencies" (Burton, Collection, p. 231).
