Ulum al Qur'an
Writing down the Revelation
While writing was not widespread among the people in Arabia at the time of the Prophet there were persons of whom it is reported that they did write. It is said for example of Waraqa, Khadija's cousin, that he had been converted to Christianity in the pre-Islamic period 'and used to write Arabic and write of the Gospel in Arabic as much as Allah wished him to write'. [Bukhari. VI. No. 478.]
The Prophet himself did much to encourage the Muslims to learn to write. It is related that some of the Quraish, who were taken prisoners at the battle of Badr, regained their freedom after they had taught some of the Muslims the art of writing.'
