Mahdist sword calligraphy

[Pieje]

I recently bought this Mahdist blade, cheap and rather out of interest.

Blade measures 70cm, forged but is rather weak.
But than again, these were not used to fight but serve a talismanic purpose.

No other marking on the blade besides the elaborate calligraphy on both sides, that seems all identical to me (and not very well written).

Any comments, eventual translation, age, tourist item or not?
Thx!
