Yemeni Jambiya/Thuma with strange markings

[mrwizard]

Thank you!

I have been sitting here with a table of the arabian alphabet and didn't recognize anything.
But now that you say it, i see the 'ain and mim. I can not, however, recognize the trailing lam. For me the last glyph looks like alif.
...maybe i should start learning arabian
