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
