[Pooya/Ali Commentary 80:13] In the original texts of all the revealed scriptures the unity (tawhid) of Allah has been clearly proclaimed. These holy books were in the hand of the angels, the prophets and the Imams who have been thoroughly purified by Allah (Ahzab : 33). The scribes have to be pious and just. The representatives of Allah are either the angels, or the prophets or the Imams of the Ahl ul Bayt.
