Arabic? inscription on a sikin panjang - translation welcome

[Loedjoe]

Can any kind and knowledgeable person please help with a transcript and translation of the inscription on this sikin panjang? I am told that it is Arabic, not Malay. I suspect from information already received that it may be a religious quotation, rather than an owner's name?? Two pictures of the inscription, in the hope that between them it will be clear enough to read. (No scabbard, by the way)
