الرقم بالرسالة.

Because Arabic often leaves out the verb to be in the present tense.

So الرقم بالرسالة literally looks like the number in the message, but it means the number is in the message.

This is very normal in both Levantine and Standard Arabic.

• Present: الرقم بالرسالة
• Past: you would need a verb, like كان الرقم بالرسالة
• Future: you would also use a verb structure

Here, بـ means something like in.

In Levantine, بـ is very common and can cover several meanings that English separates out, such as:

• in
• at
• with
• sometimes by

So in this sentence, بالرسالة means in the message.

Because بـ is a prefix in Arabic, not a separate word.

So it attaches directly to the noun:

• بـ
  • الرسالة = بالرسالة

This is standard Arabic spelling.

Because of the ر in الرسالة.

The ر is a sun letter, so the ل of الـ is not pronounced clearly. Instead, the next consonant is doubled.

So although it is written بالرسالة, it is pronounced more like:

• bir-risāle in Levantine-style pronunciation
• more formally bi-r-risālah

That doubling of r is completely normal.

Because both nouns are definite:

• الرقم = the number
• الرسالة = the message

So the sentence is specifically about a known number and a known message.

If you removed ال, the meaning would become less definite and would sound different.

In many Levantine accents, ق is often pronounced as a glottal stop, so الرقم may sound like:

• er-ra'em

In a more formal or careful pronunciation, you may hear:

• ar-raqm

So in everyday Levantine, the whole sentence may sound roughly like:

• er-ra'em bir-risāle

Exact pronunciation depends on region and speaker.

Yes, رسالة is natural and fully understandable.

Depending on context, it can mean:

• message
• text message
• letter

In very casual speech, especially for phone/chat texting, many Levantine speakers also use borrowed words like:

• مسج
• ميسج

So you might also hear:

• الرقم بالمسج

That sounds more colloquial and modern.

It works in both.

Why?

• The structure is simple and natural in Arabic generally.
• الرقم بالرسالة is not strongly marked as only dialect or only formal Arabic.

That said, in very everyday Levantine, people might also say things like:

• الرقم موجود بالرسالة
• الرقم بالمسج

So the sentence you have is fine, but it feels a little neutral rather than strongly dialect-heavy.

Yes, absolutely.

في الرسالة also means in the message.

The difference is mostly style:

• بالرسالة sounds very natural in Levantine
• في الرسالة is also correct, but can sound a bit more literal or a bit less colloquial in some contexts

So both are understandable and correct.

It depends on context.

رسالة can refer to:

• a text message
• a written message
• a letter
• sometimes an email or direct message, depending on the situation

So the word itself is broad, and the surrounding context tells you what kind of message is meant.

In Levantine, a common negative version would be:

• الرقم مو بالرسالة
• or الرقم مش بالرسالة

Both are used, depending on region and speaker.

If you want to sound a bit more explicit, you can say:

• الرقم مو موجود بالرسالة

That means the number isn’t in the message.

Yes.

You can say:

• الرقم موجود بالرسالة

This makes the sentence a little fuller and more explicit, like the number is موجود / present / there in the message.

Without موجود, the original sentence is still completely normal. It is just shorter and more compact.
