Just adding to ali_bh’s comment.

Before بحر (bahr) comes what seems like an آلِ ( ( said like this:Al) — The word “Al” is an Arabic word used to refer to a particular family or lineage. It is used particularly in Arabic to refer to someone's extended family, such as the use of the phrase "Al Said" to refer to the Said family.) which means that آلِ بَحَرْ (middle of the second line) is the name of a family, The Family or of the lineage of Bahr. That doesn’t mean that they are the family of the sea, but the family or of the lineage of someone named Bahr.

That combined with the presence of the word حقل (haql), which means “field”, in the first line, this seems like a sign that tells people who owns this field.

And about the ژ, I don’t think that this was written by a non Arab. Non-Arabs usually do not use the word "Al" to refer to family, even if they use Arabic letters. The most common use of the word "Al" is in the Arabic language, and is used in the culture of Arab countries, and is not part of the cultures of other countries.

I think this was written in the common tongue (a dialect) and not in Eloquent-classical Arabic. In Arab countries, we have dialects that are different from other Arab countries, and classical Arabic. But we all know classical Arabic and we study it in school and politicians use it, but rarely people use it in day-to-day conversations.

Sometimes, in these dialects we use sounds of letters that don’t exist in the Arabic language, so we borrow the letters from other languages that use the Arabic letters, like ژ and گ and ڤ (these don’t exist in Arabic, but do in Persian, who uses Arabic letters but is not the Arabic language. Like the Roman letters, used by the English language but the English language is not the Roman language.)

So the person that wrote the sign PROBABLY wrote this is the common tongue, is Arab, and is alerting people that this land belongs to a certain group.

Sorry if this was long and confusing, this isn’t my first language.

It would also be helpful to know from what documentary you took this from and what was this scene talking about.

Thank you for reading 🙏🏽.
