favoured for its legibility. The eleventh century Quran is one of the earliest dated manuscripts in this style. This "new style" is defined by breaks and angular forms and by extreme contrasts between the thick and thin strokes. The script was initially used in administrative and legal documents, but then it replaced earlier Quranic scripts. It is possible that it was easier to read than the early 'Abbasid scripts, which differ greatly from current writing. Economic factors may also have played a part because while the "new style" was being introduced, paper was also beginning to spread throughout the Muslim world, and the decrease in the price of books triggered by the introduction of this new material seems to have led to an increase in its demand. The "new style" was the last script to spread throughout the Muslim world before the introduction of printing. It remained in use until the 13th century, at which point it was restricted to titles only. 1924 Cairo edition The influential standard Quran of Cairo ("1342 Cairo text" using the Islamic calendar) is the Quran that was used throughout almost all the Muslim world until the Saudi Quran of 1985.

The Cairo edition has become the standard for modern printings of the Quran with the exception of those used in all North Africa (excluding Egypt) where the Warsh version is used. A committee of leading professors from Al-Azhar University had started work on the project in 1907 but it was not until 10 July 1924 that the "Cairo Qur’an" was first published by Amiri Press under the patronage of Fuad I of Egypt, as such, it is sometimes known as the "royal (amīriyya) edition." The goal of the government of the newly formed Kingdom of Egypt was not to delegitimize the other qir’at, but to eliminate that, which the colophon labels as errors, found in Qur’anic texts used in state schools. To do this they chose to preserve one of the fourteen Qira'at “readings”, namely that of Hafs (d. 180/796), student of ‘Asim. Its publication has been called a "terrific success", and the edition has been described as one "now
