You will never find a Christian missionary talking about the preservation of Holy Qur’an and then failing to come up with issue of the surahs missing from Ibn Mas’ud’s mushaf.
Surahs missing in Ibn Mas’ud’s Mushaf:
It is said that Ibn Mas’ud’s mushaf (codex) did not have three surahs, al-Fatiha and al-mu’awwazatayn (al-Falaq and al-Nas) i.e. Nos. 1, 113 & 114. (See al-Ittiqan 1/270 al-Haiyaal-Misriya, Cairo, 1974)
