In 1972, in a mosque in the city of Sana'a, Yemen, manuscripts were discovered that were later proved to be the most ancient Quranic text known to exist at the time. The Sana'a manuscripts contain palimpsests, a manuscript page from which the text has been washed off to make the parchment reusable againa practice which was common in ancient times due to scarcity of writing material. However, the faint washed-off underlying text (scriptio inferior) is still barely visible and believed to be "pre-Uthmanic" Quranic content, while the text written on top (scriptio superior) is believed to belong to Uthmanic time. Studies using radiocarbon dating indicate that the parchments are dated to the period before 671 AD with a 99 percent probability.
Before which year were the Sana'a manuscripts produced?
671 AD

The jat-reflex rules are not without exception. For example, when short jat is preceded by r, in most Ijekavian dialects developed into /re/ or, occasionally, /ri/. The prefix pre- ("trans-, over-") when long became pre- in eastern Ijekavian dialects but to prije- in western dialects; in Ikavian pronunciation, it also evolved into pre- or prije- due to potential ambiguity with pri- ("approach, come close to"). For verbs that had -eti in their infinitive, the past participle ending -el evolved into -io in Ijekavian Neostokavian.
Why did pre or prije develop rather than the symboled "pre"?
due to potential ambiguity with pri

After World War I, when Britain and France divided up the Middle East's countries, apart from Turkey, between them, pursuant to the Sykes-Picot agreementin violation of solemn wartime promises of postwar Arab autonomythere came an immediate reaction: the Muslim Brotherhood emerged in Egypt, the House of Saud took over the Hijaz, and regimes led by army officers came to power in Iran and Turkey. "[B]oth illiberal currents of the modern Middle East," writes de Bellaigne, "Islamism and militarism, received a major impetus from Western empire-builders." As often happens in countries undergoing social crisis, the aspirations of the Muslim world's translators and modernizers, such as Muhammad Abduh, largely had to yield to retrograde currents.
What did the aspirations of the Muslim world's translators find themselves yielding to?
