The Sana'a manuscript is one of the oldest known copies of the Quran, dating back to the early 8th century. The manuscript contains some differences and variations in the text compared to the standard Uthmanic text of the Quran that is commonly used today. However, it is important to note that these differences are minor and do not affect the fundamental beliefs and teachings of the Quran.
While there are some scholars who have studied the differences between the Sana'a manuscript and the standard Uthmanic text, there is no complete list of differences that can be considered authoritative or comprehensive. This is because the Sana'a manuscript is not a standardized text, and there are variations in the text between different pages and sections of the manuscript.
In general, the differences between the Sana'a manuscript and the Uthmanic text are primarily related to spelling and grammar, rather than meaning. For example, there may be differences in the placement of diacritical marks, the use of certain letters, or the arrangement of words and phrases. However, these differences do not affect the overall message and teachings of the Quran.
It is worth noting that the Quran has been transmitted orally and in writing through various channels since the time of Prophet Muhammad, and there have been minor variations in the text over time. However, Islamic scholars have developed a rigorous system of textual criticism and verification to ensure the authenticity and accuracy of the Quranic text.
In conclusion, while there are some minor differences between the Sana'a manuscript and the standard Uthmanic text of the Quran, these differences do not affect the fundamental beliefs and teachings of the Quran. Islamic scholars have developed a rigorous system of textual criticism and verification to ensure the authenticity and accuracy of the Quranic text, and the differences between the Sana'a manuscript and the standard Uthmanic text are considered minor and inconsequential.
