Rethinking Criteria - Shorter CWANA "Reading" List
Applying the revised critera (see here), the CWANA list becomes clear. The issues have always been whether it should be Ibn Sina or al-Ghazali, or whether it is Shahnama or Rumi.
With the revised criteria, it is clear that al-Ghazali trumps Ibn Sina because of modern continued readership, and Shahnama trumps Rumi because it is at the root of the Persian literary tradition.
So the 4 texts are: Qur'an, al-Tabari, al-Ghazali, Shanama.
