BIBLE NOT TRANSLATED INTO ARABIC UNTIL THE 8TH CENTURY CE
The Arabic NT also belongs to the eastern branch of translations. Translations 
into Arabic prior to the seventh century are not known, and there is no uniformity 
of versions. Some were translated from the Syriac, and still others from Coptic. 
Since the Arabic versions are so late they are not useful as witnesses to the 
original text of the NT; they are, of course, exceedingly useful for the mission 
of the church to Arabic-speaking peoples.
