Pre-Islamic Arabia
In Pre-Islamic Arabia, the society during the time of Muhammad was predominantly oral, and for this reason he would recite the Quranic verses to his Companions for them to memorize. Therefore, it is unknown whether the Quran was ever written and collected during the time of Muhammad. While writing was not a common skill during Muhammad's time, Mecca, being a commercial center, had a number of people who could write. Some scholars believe that several scribes including Zayd ibn Thabit and Ubay ibn Ka'b recorded verses of the Quran. This provides an explanation as to how the Quran existed in written form during the life of Muhammad, even if it was not compiled into one text. According to one source, "sira" (prophetic biography) of Muhammad list the following as scribes of the Quran: Abu Bakr al-Siddeeq, ‘Umar ibn al-Khattaab, ‘Uthmaan ibn ‘Affaan, ‘Ali ibn Abi Taalib, al-Zubayr ibn al-‘Awwaam, ‘Aamir ibn Fuhayrah, ‘Amr ibn al-‘Aas, Ubayy ibn Ka’b, ‘Abd-Allaah ibn al-Arqam, Thaabit ibn Qays ibn Shammaas, Hanzalah ibn al-Rabee’ al-Usaydi, al-Mugheerah ibn Shu’bah, ‘Abd-Allaah ibn Rawaahah, Khaalid ibn al-Waleed, Khaalid ibn Sa’eed ibn al-‘Aas (whom it was said was the first one to write down anything for him), Mu’aawiyah ibn Abi Sufyaan and Zayd ibn Thaabit.
