Help requested on Islamic? inscriptions on a heavy axe

[Dom]

the calligraphy don't give any information,

as far as is purely religious mentions,
it's obligatory in Arabic language,
even if the country of origin is not arabic speakers, e.i.; Persia, India

due to what is mentionned on above
no ideas from where it's could come from

without to take a big risk (I'm ready to put one nail on the block under the blade)
it's Indo-Persian
even more Indo than Persan

now I leave the place to my collegues, who could have their appreciations
