Which female companion safeguarded the first compiled manuscript of the Holy Quran?

Explanation: After the Holy Quran was compiled during the caliphate of Hazrat Abu Bakr (RA) under the supervision of Hazrat Zaid bin Thabit (RA), the manuscript was preserved by Hazrat Abu Bakr (RA), then Hazrat Umar (RA), and later entrusted to Hazrat Hafsa bint Umar (RA). During the caliphate of Hazrat Uthman (RA), this manuscript served as the reference for preparing standardized copies of the Holy Quran, making Hazrat Hafsa (RA) an important guardian of the first compiled text.
