The Sana'a manuscript refers to a collection of ancient Islamic texts discovered in 1972 during restoration work at the Great Mosque of Sana'a, Yemen. This manuscript is significant because it contains some of the oldest known copies of the Qur'an, dating back to the 7th century. The texts are written in an early Arabic script, providing valuable insights into the early development of the Islamic tradition. Researchers have found that the Sana'a manuscript includes variations in the text compared to the standardized version of the Qur'an used today. These differences have sparked interest in the study of Qur'anic transmission and the historical context of early Islamic texts. The manuscript is now considered a crucial artifact for understanding the evolution of Islamic scripture.
