Writing did not spread in the Arabs except with the advent of Islam, so the writers of revelation appeared, who were counted by some scholars, reaching more than forty companions. The matter of writing remained limited to writing verses of the Qur’an and writing the hadiths of the Messenger, may God bless him and grant him peace, until the area of the Islamic state expanded during the time of the Umayyads, and a major breakthrough began in writing and codification, especially during the era of Caliph Omar bin Abdul Aziz; Omar has been using God for forty days to write down the hadith of the Messenger of God, may God bless him and grant him peace.
