Modern Arabic is always written with the ''i‘jām'' - consonant pointing, but only religious texts, children's books and works for learners are written with the full ''tashkīl'' - vowel guides and consonant length. It is not uncommon for authors to add diacritics to a word or letter when the grammatical case or the meaning is deemed otherwise ambiguous. In addition, classical works and historic documents rendered to the general public are often rendered with the full tashkīl, to compensate for the gap in understanding resulting from stylistic changes over the centuries.
Tashkil (marks used as phonetic guides)
The literal meaning of ' is 'forming'. As the normal Arabic text does not provide enough information about the correct pronunciation, the main purpose of ' (and ') is to provide a phonetic guide or a phonetic aid; i.e. show the correct pronunciation. It serves the same purpose as

Harakat (short vowel marks)
The ' , which literally means 'motions', are the short vowel marks. There is some ambiguity as to which ' are also '; the ', for example, are markers for both vowels and consonants.
The is a small diagonal line placed ''above'' a letter, and represents a short (like the /a/ sound in English word "cat"). The word ' itself () means ''opening'' and refers to the opening of the mouth when producing an . For example, with ''
'' (henceforth, the base consonant in the following examples): .
When a is placed before a plain letter (''
'') (i.e. one having no hamza or vowel of its own), it represents a long (close to the sound of "a" in the English word "dad", with an open front vowel /æː/, not back /ɑː/ as in "father"). For example: . The ' is not usually written in such cases. When a fathah placed before the letter ⟨⟩ (yā’), it creates an (as in "lie"); and when placed before the letter ⟨⟩ (wāw), it creates an (as in "cow").
Although paired with a plain letter creates an open front vowel (/a/), often realized as near-open (/
/), the standard also allows for variations, especially under certain surrounding conditions. Usually, in order to have the more central (/ ä
/) or back (/ ɑ
/) pronunciation, the word features a nearby back consonant, such as the emphatics, as well as ''
'', or ''
''. A similar "back" quality is undergone by other vowels as well in the presence of such consonants, however not as drastically realized as in the case of .
[Karin C. Ryding, "A Reference Grammar of Modern Standard Arabic", Cambridge University Press, 2005, pgs. 25-34, specifically “Chapter 2, Section 4: Vowels”]
A similar diagonal line ''below'' a letter is called a and designates a short (as in "me", "be") and its allophones , ɪ, e, e̞, ɛ
(as in "Tim", "sit"). For example: .
When a ' is placed before a plain letter (''
''), it represents a long (as in the English word "steed"). For example: . The ' is usually not written in such cases, but if ''
'' is pronounced as a diphthong , ' should be written on the preceding consonant to avoid mispronunciation. The word ' means 'breaking'.
The is a small curl-like diacritic placed above a letter to represent a short /u/ (as in "duke", shorter "you") and its allophones , ʊ, o, o̞, ɔ
(as in "put", or "bull"). For example: .
When a is placed before a plain letter ('), it represents a long (like the 'oo' sound in the English word "swoop"). For example: . The ' is usually not written in such cases, but if ' is pronounced as a diphthong , ' should be written on the preceding consonant to avoid mispronunciation.
The word ''ḍammah'' (ضَمَّة) in this context means ''rounding'', since it is the only rounded vowel in the vowel inventory of Arabic.
The superscript (or dagger) '
('), is written as short vertical stroke on top of a consonant. It indicates a long sound for which ''
'' is normally not written. For example: (') or (').
The dagger ' occurs in only a few words, but they include some common ones; it is seldom written, however, even in fully vocalised texts. Most keyboards do not have dagger ''.'' The word

In theory, the same sequence could also be represented by two 's, as in *, where a hamza above the first ' represents the while the second ' represents the . However, consecutive 's are never used in the Arabic orthography. Instead, this sequence must always be written as a single ' with a ' above it, the combination known as an '. For example: .

The , or looks like a small letter '' '' on top of an ' (also indicated by an ' without a '). It means that the ' is not pronounced when its word does not begin a sentence. For example: ('), but (''imshū'' not ''mshū''). This is because no Arab word can start with a vowel-less consonant (unlike the English ''school'', or ''skateboard''). But when it happens, an ''alif'' is added to obtain a vowel or a vowelled consonant at the beginning of one's speech. In English that would result in *''ischool'', or *''iskateboard''.
It occurs only in the beginning of words, but it can occur after prepositions and the definite article. It is commonly found in imperative verbs, the perfective aspect of verb stems VII to X and their ('). The ''alif'' of the definite article is considered a '.
It occurs in phrases and sentences (connected speech, not isolated/dictionary forms):
* To replace the elided hamza whose alif-seat has assimilated to the previous vowel. For example: or (') ‘in Yemen’.
* In hamza-initial imperative forms following a vowel, especially following the conjunction (') ‘and’. For example: َ (') ‘rise and then drink the water’.

I‘jām (phonetic distinctions of consonants)
The ''i‘jām'' (sometimes also called ''nuqaṭ'') are the diacritic points that distinguish various consonants that have the same form ('), such as ب, ت, ث, ن, and ي. Typically ''i‘jām'' are not considered diacritics but part of the letter.
Early manuscripts of the '''' did not use diacritics either for vowels or to distinguish the different values of the ''.'' Vowel pointing was introduced first, as a red dot placed above, below, or beside the ', and later consonant pointing was introduced, as thin, short black single or multiple dashes placed above or below the ''rasm'' (

Hamza (glottal stop semi-consonant)
Although often a diacritic is not considered a letter of the alphabet, the hamza (', ), often stands as a separate letter in writing, is written in unpointed texts and is not considered a ''.'' It may appear as a letter by itself or as a diacritic over or under an ', ', or '.
Which letter is to be used to support the ' depends on the quality of the adjacent vowels;
* If the glottal stop occurs at the beginning of the word, it is always indicated by hamza on an ': above if the following vowel is or and below if it is .
* If the glottal stop occurs in the middle of the word, ' above ' is used only if it is not preceded or followed by or :
** If is before or after the glottal stop, a ' with a ' is used (the two dots which are usually beneath the ' disappear in this case): .
** Otherwise, if is before or after the glottal stop, a ' with a ' is used: .
* If the glottal stop occurs at the end of the word (ignoring any grammatical suffixes), if it follows a short vowel it is written above ', ', or ' the same as for a medial case; otherwise on the line (i.e. if it follows a long vowel, diphthong or consonant).
* Two 's in succession are never allowed: is written with '' '' and is written with a free ' on the line .
Consider the following words: ("brother"), ("Ismael"), ("mother"). All three of above words "begin" with a vowel opening the syllable, and in each case, ' is used to designate the initial glottal stop (the ''actual'' beginning). But if we consider ''middle'' syllables "beginning" with a vowel: ("origin"), ("hearts" — notice the syllable; singular ), ("heads", singular ), the situation is different, as noted above. See the comprehensive article on ' for more details.
According to tradition, the first to commission a system of ''harakat'' was
Ali ibn Abi Talib ( ar, عَلِيّ ٱبْن أَبِي طَالِب, ; 13 September 601 – 29 January 661) was a cousin, son-in-law and companion of the Prophets and messengers in Islam, Islamic prophet Muhammad in Islam, Muhammad, who ru ... who appointed Abu al-Aswad al-Du'ali

Abu al-Aswad devised a system of dots to signal the three short vowels (along with their respective allophones) of Arabic. This system of dots predates the ', dots used to distinguish between different consonants.

Abu al-Aswad's system
Abu al-Aswad's system of Harakat was different from the system we know today. The system used red dots with each arrangement or position indicating a different short vowel.
A dot above a letter indicated the vowel ', a dot below indicated the vowel ', a dot on the side of a letter stood for the vowel ', and two dots stood for the '' ''.
However, the early manuscripts of the Qur'an did not use the vowel signs for every letter requiring them, but only for letters where they were necessary for a correct reading.
Al Farahidi's system
The precursor to the system we know today is Al Farahidi's system. '' '' found that the task of writing using two different colours was tedious and impractical. Another complication was that the ' had been introduced by then, which, while they were short strokes rather than the round dots seen today, meant that without a color distinction the two could become confused.
Accordingly, he replaced the ' with small superscript letters: small alif, yā’, and wāw for the short vowels corresponding to the long vowels written with those letters, a small ''s(h)īn'' for ''shaddah'' (geminate), a small ''khā’'' for ''khafīf'' (short consonant; no longer used). His system is essentially the one we know today.
