التفويض ساري المفعول، والختم الرسمي على إيصال الاستلام.

Because this is a nominal sentence in the present tense. In Modern Standard Arabic, the verb to be is usually not written or spoken in simple present-tense statements.

So:

• التفويض ساري المفعول = The authorization is valid / in force
• الختم الرسمي على إيصال الاستلام = The official stamp is on the receipt of acknowledgment

Arabic simply puts the subject and predicate next to each other when the meaning is present-tense is/are.

التفويض means authorization, delegation, or sometimes power of attorney/letter of authorization, depending on context.

In this sentence, it most likely refers to a specific authorization document or official authorization already known from the context.

A learner should also notice:

• تفويض = authorization/delegation
• التفويض = the authorization

The الـ makes it definite.

ساري المفعول is a very common formal/bureaucratic expression meaning:

• valid
• effective
• in force
• currently in effect

You will often see it with:

• laws
• permits
• contracts
• certificates
• official documents

So التفويض ساري المفعول means the authorization is still legally or officially valid.

It is both a set phrase and something with grammar worth noticing.

It functions as a fixed formal expression, but grammatically it is commonly analyzed as a kind of iḍāfa-like combination:

• ساري = current / effective / in force
• المفعول = effect

Together, the phrase means something like having effect or in effect, but in natural English you should translate it as valid or in force, not word-for-word.

So for learning purposes, it is best to memorize ساري المفعول as a whole expression.

The و simply means and.

It links two short formal statements:

• التفويض ساري المفعول
• الختم الرسمي على إيصال الاستلام

In document language, Arabic often strings together short factual notes in this way. It can sound a little like a checklist or administrative statement.

الختم الرسمي means the official stamp or the official seal.

Word by word:

• الختم = the stamp / the seal
• الرسمي = official

So this refers to the authorized institutional stamp, not just any mark on the page.

A useful note:

• رسمي is masculine, because ختم is masculine.
• If the noun were feminine, the adjective would also change.

على usually means on.

Here it is used because the stamp is physically on the document. That is the natural preposition for a stamp, signature, or mark placed on paper.

So:

• الختم الرسمي على إيصال الاستلام = the official stamp is on the acknowledgment receipt

Using في would suggest something more like in the receipt, which is not the intended idea here.

إيصال الاستلام is an iḍāfa construction.

It is made of:

• إيصال = receipt, slip, voucher
• الاستلام = receiving, receipt, acceptance of delivery

Together, the phrase means something like:

• receipt of receipt
• acknowledgment of receipt
• delivery receipt

In English, the most natural translation is usually acknowledgment of receipt or receipt confirming delivery/receipt.

Grammar point: In an iḍāfa construction:

• the first noun usually does not take الـ
• the second noun can carry the definiteness

So إيصال الاستلام is a classic noun + noun construction.

Yes, you can understand it as a slightly elliptical or compressed formal statement.

Arabic administrative style often leaves out words that are easy to infer. The second part could be expanded mentally as something like:

• والختم الرسمي موجود على إيصال الاستلام
• والختم الرسمي موضوع على إيصال الاستلام

That would mean:

• and the official stamp is present on the acknowledgment receipt
• and the official stamp is placed on the acknowledgment receipt

But the shorter version is perfectly normal in formal written Arabic.

A possible full vocalization is:

التَّفْوِيضُ سَارِي الْمَفْعُولِ، وَالْخَتْمُ الرَّسْمِيُّ عَلَى إِيصَالِ الِاسْتِلَامِ

The main case relationships are:

• التفويضُ: nominative, because it is the subject of the first nominal sentence
• ساري المفعولِ: the predicate; المفعولِ is genitive within the expression
• الختمُ الرسميُّ: nominative, as the subject of the second nominal sentence
• على إيصالِ الاستلامِ: both nouns are genitive, because إيصال follows the preposition على, and الاستلام is the second term of the iḍāfa

Even if case endings are not written in normal texts, understanding them helps you parse the sentence.

A careful reading would be approximately:

at-tafwīḍ sārī al-mafʿūl, wal-khatm ar-rasmī ʿalā īṣāl al-istilām

A few pronunciation notes:

• التفويض is pronounced at-tafwīḍ, not al-tafwīḍ, because ت is a sun letter
• الرسمي is pronounced ar-rasmī, not al-rasmī, because ر is also a sun letter
• الختم keeps the l sound of الـ, because خ is a moon letter
• إيصال begins with a long ī sound

If you are reading in pause, you would normally drop the final case vowels in actual speech.

Yes. It sounds very formal, official, and document-like.

Expressions such as:

• ساري المفعول
• الختم الرسمي
• إيصال الاستلام

belong to the language of:

• administration
• legal paperwork
• government forms
• official correspondence

So this is excellent vocabulary for reading documents, but it is not the kind of phrasing you would usually hear in casual conversation.
