legends about the King Fuʾād Edition aka the CE

the KFA is the first printed qurʾān by and for Muslims
the KFA fixed an ill-defined text
the KFA made Ḥafs ʿan ʿĀṣim predominant

the KFA was an immediate success all ober the Muslim world
... was the first printed muṣḥaf following the rasm al-ʿuṯmānī
... was the child of an Azhar committee
The committee worked 17 years on its text
... was the necessary reaction to tons of mistakes in importandt maṣāḥif (which had to be sunk in the Nile)
the source for rasm are not manuscripts, but the literature about it; it is therefore a reconstruction, the result of a rewriting of the usual text (Bergsträßer)
it follows Abū Daʾūd Sulaimān Ibn Naǧāḥ

the taʿrīf says: ad-Dānī and Ibn Naǧāḥ, and when they disagree: Ibn Naǧāḥ (hence Ibn N.)
