‘Understanding after ambiguity’
Date: Unknown, but before Kitāb al-ʿilm wa-l-ʿamal
Original Language: Arabic
The work is no longer extant. Yūḥannā mentions it several times in Kitāb al-ʿilm wa-l-ʿamal, and it would seem that it was a theological/apologetic work, defending Christian doctrines from Islamic challenges.
Nothing can be said without more information about the work.
