) are
used as long vowels or diphthongs and also play a role as weak
consonants. To help those who are not
well verse in Arabic Grammar, the vowels signs have been developed for
those who are learning Arabic as second language.VOWELS:
In any vocalized language vowels plays important role, it is the most prominent and central sound of a syllable. The vowels helps us to join letter so a full sound can be achieved.
In English a,e,i,o and u
(also y ) are
the vowels which are clearly spelled out in a text whereas in
Arabic they are not. There are no exact correspondences between English and
Arabic vowels; they may differ in quality, and they may behave differently under
certain circustances. There are 29 letters in Arabic alphabets which all are consonants but
( letter alif, waw and Ya ) are
used as long vowels or diphthongs and also play a role as weak
consonants. To help those who are not
well verse in Arabic Grammar, the vowels signs have been developed for
those who are learning Arabic as second language.
The vowels sings such as 
(desinential marks or diacritics) are not part of Arabic letters,. The short vowels are merely oral, and used
only in teaching texts for guiding the learner, and they mainly appear in important religious
texts but rarely appear on everyday writing such as newspaper, text books etc. In non-religious writing such as journals,
newspapers etc. vowel signs often
omitted and similar words may have to be interpreted from the context,
vowels sign are only indicated when there is possibility of
confusion. As
far as Qur'an concern these vowels signs are absolutely
necessary in this age in order to pronounced religious text for those who are not well versed in
classical Arabic language.
Over time the oral Arabic language has changed drastically from the Arabic language spoken at the time of the Prophet. Consequently, the Arab have to study the art of tajweed (the accent ) just the same way that non-Arabs do.
The vowels signs which were
developed approximately 150 years after the demise of the Holy Prophet (s.a.w.)
serve the same purpose as one may find the pronunciation key in any standard English
dictionaries for example the word Qur'an may be found in a dictionary
like 
. unlike in English
the pronunciation key or vowel signs are fairly standard and uniform and appears in
important religious text such as Holy Qur'an or Hadith whereas in English the pronunciation
key are restricted to the dictionaries only.
The vowels helps us to join consonant so a full sound can be achieved. In English there are five (5) vowels letters ie. (a,e,i,o.u) whereas in Arabic there are two kind of vowels
Those who are well versed in Arabic language also preferred the read the the Holy Qur'an with the vowels and other signs so not to make any mistake in reciting the Holy Qur'an.
