The Scribes of the Holy Qur'an
Whilst mentioning the names of the scribes of the Holy Quran, Hazrat Khalifatul Masih II (ra) states:
“As soon as a revelation was received by the Holy Prophet (sa) it was recorded in writing from his dictation. A number of persons are known to have been assigned by the Holy Prophet (sa) for this purpose. Of these the names of the following fifteen have been mentioned in historical accounts; Zaid bin Thabit (ra), Ubayy bin Ka‘b (ra), Abdullah bin Sa‘d bin Abi Sarh (ra), Zubair bin al-Awwam (ra), Khalid bin Saeed bin al-Aas (ra), Abaan bin Saeed al-Aas (ra), Hanzla bin Rabi al-Asadi (ra), Muayqib bin Abi Fatima (ra), Abdullah bin Arqam az-Zuhri (ra), Sharahbeel bin Hasana (ra), Abdullah bin Rawaha (ra), Hazrat Abu Bakr (ra), Hazrat Umar (ra), Hazrat Uthman (ra) and Hazrat Ali (ra). Whenever the Holy Prophet (sa) received a revelation, he would send for one of these persons and dictate to him the text of the revelation he had received.”
