Caucasian Kinjal Dagger Questions
 

I have this Kinjal (Bebut dagger?). In my collection. Interesting looking hilt. Hilt represents an animal. There are three Russian proofmarks on the blade and the date '1891' so I know the Kinjal was made around that time (most likely in Dagestan or maybe Tiflis, Georgia?). But it's the etching on the blade I'm having a difficult time translating (Persian Arabic calligraphy? Thuluth of Naskh script?). I entered the script through AI translation and I got: Work of Ahmad and "O Allah". I've read that Praises/invocations from the Koran/hadiths are pretty common for these types of weapons. What do you guys think? Ideas?
