Hafsah bint 'Umar was the daughter of 'Umar ibn al-Khattab and a Mother of the Believers. She could read and write.
After many Companions who knew the Quran by heart were martyred at al-Yamamah, Abu Bakr had the Quran gathered on written pages. Those pages stayed with Abu Bakr, then with 'Umar, and after his death with Hafsah.
❝ HadithIn 'Uthman's time, when differences arose in recitation in various regions, he sent word to Hafsah: send us the pages, so that we may copy them into mushafs and return them to you. Hafsah sent them, and when the copying was done the pages were returned to her.Sahih al-Bukhari 4987 · Sahih
