Al-Fā'il — The Doer
The agent of the verb — always in raf', hidden inside the verb or named after it. The key to reading any verbal sentence.
Who Did It?
Every verbal sentence answers the question "who did the action?" — and the answer is the fā'il (اَلْفَاعِل), the doer. It is the second essential component of the jumlah fi'liyyah, following the verb. One rule governs it absolutely:
The doer (al-fā'il) is always in the RAF' state — without exception. A pronoun doer is embedded in the verb; a noun doer follows the verb in raf'.
Two Types of Doer
The internal pronoun. Every conjugated verb already contains a doer. In sighas 1 and 4 it is mustatir — hidden — standing for هُوَ or هِيَ. In all other sighas it is bāriz — visible — as a suffix: the waw in ذَهَبُوا (they went), the تُ in ذَهَبْتُ (I went). Note that the تْ in ذَهَبَتْ marks femininity only; it is not the doer — the doer (هِيَ) remains hidden.
The external noun. When the agent is named, a noun is placed after the verb in raf': ذَهَبَ حَامِدٌ — Hamid went. When an external noun appears, it cancels the internal pronoun in translation — there is only ever one doer per verbal sentence. ذَهَبُوا الطُّلَّابُ (two doers) is simply incorrect Arabic.
The Gender Rule
External MASCULINE doer → sigha 1 (نَصَرَ زَيْدٌ — Zayd helped) External FEMININE doer → sigha 4 (نَصَرَتْ فَاطِمَةُ — Fatima helped) The NUMBER of the doer — singular, dual or plural — never changes the verb form.
So: نَصَرَ مُسْلِمٌ، نَصَرَ مُسْلِمَانِ، نَصَرَ الْمُسْلِمُونَ — one Muslim, two Muslims, all the Muslims helped, and the verb never moves from sigha 1.
The Fā'il as a Phrase
The doer need not be a single word. Any phrase from Book One can fill the fā'il slot, with its first word in raf': a descriptive phrase (ذَهَبَ الطَّالِبُ الْجَدِيدُ — the new student went), a demonstrative phrase (ذَهَبَ ذَلِكَ الطَّالِبُ), an idafah (ذَهَبَ شَيْخُ الْعِرَاقِ — the scholar of Iraq went), a relative clause, or a conjunctive phrase (ذَهَبَ الْمُعَلِّمُ وَالطَّالِبُ). The one structure that can never be fā'il is the jar-majroor — it attaches to the verb as muta'alliq instead.
Special Cases
Four cases permit either sigha 1 or sigha 4: rational broken plurals (ذَهَبَ الرِّجَالُ or ذَهَبَتِ الرِّجَالُ), collective nouns (الْقَوْمُ), non-real feminines (الشَّمْسُ), and a real feminine doer separated from its verb by another word.
One case is fixed: non-rational plurals are always treated as feminine singular — جَلَسَتِ الْجِمَالُ (the camels sat) requires sigha 4, even though جَمَل is masculine in the singular. This rule echoes throughout Arabic agreement, from verbs to adjectives to pronouns.

Frequently Asked Questions
What is the difference between the fa'il and the English subject?
The English subject comes before its verb; the fā'il comes after (or inside) it. More deeply, the fā'il is defined by case — it is the noun in raf' attached to the action — not by position. That is why Arabic word order can flex without ambiguity.
How can the doer be "hidden"?
In sighas 1 and 4 (ذَهَبَ، ذَهَبَتْ) no suffix marks the doer, yet the meaning "he went" / "she went" is complete. The grammarians say the doer is mustatir — present in meaning, invisible in form. Every verb has a doer; you just cannot always see it.
Why does the Quran sometimes use a feminine verb with a masculine plural noun?
Two reasons: non-rational plurals are obligatorily treated as feminine singular, and rational broken plurals or collectives may optionally take sigha 4. Both are standard rules of the fā'il, not irregularities.
