apparently "a date of A.H. 608" is inscribed somewhere on this tile. could someone find it and point out where it is?

it should be trivial, and i am familiar with the arabic script (the image has perso-arabic) but not when it's written in such a calligraphic manner.

responses won't be that useful after 11:59 pm 4chan time, although i would still be curious to know
