Arabic was the language common to the entire Arabian Peninsula. And, obviously in different regions and tribes, were set dialects.
The Prophet Muhammad, therefore, received the revelation in the Arabic language spoken by the Bani Quraish of Mecca. Neophytes, at first, to facilitate the understanding and propagation of Islamic Faith recite the Quran with their respective dialects. But with the spread of Islam, beyond the regions of Arabic, the Arabic language was gaining ground, and to avoid misunderstandings and misrepresentations, the Caliph Othman, in consultation with the companions of the Prophet, decided that the certified copies of Quran compiled by Abou Baker should be the only valid, because the exact text of the revelation in the entire Muslim World.
The different ways of reciting the Quran:
We consider below the different ways of reciting the Koran.
1) The Arabic script used by scribes of the Prophet had no points or vowels. The same kind of writing was used in compiling written by Zaid, under the caliphate of Abu Baker and the copies distributed by the Caliph Othman.
2) Although the Koran faithfully collected, copied and safeguarded, because of illiteracy prevailing-at the beginning of the preaching of its spread was done orally. Educated Arabs had no difficulty reading it. But there were thousands of believers who had learned the Koran by heart listening to the Prophet and his companions to recite. And so on and so passed reciting other Muslims.
3) Othman, not only sent a copy of the Koran authentic to each region of the Islamic world, but to preserve the correct reading, a reader sent “Qari” (4) to each region to disseminate the correct recitation of the Prophet taught same.
4) Over time it got the need to use appropriate voice and a score for the preservation of a correct reading of the Koran.
Thus it was at the request of Zaid (45 to 53 D. Hj.) Which fixed the vowels and punctuation. Then, during the reign of Abdel Malek (65 to 85 D. Hj.) Hadjadj-BinYusuf, some were responsible for assigning new signs for the score. And vocal for absolute clarity that preserve and improve readability.
Consequently, after the above, it is evident that the recitation of the Qur’an (with few minor variations) is the same as performed and taught the Prophet. This is affirmed unanimously by all the scholars and reciters (5) of the Koran believe that only the recitation of the Qur’an is authentic.
a) match the text of the copies distributed by the Caliph Othman.
b) Conforms to the Arabic lexicon, its usos9 your language and grammar.
c) It is quite faithful to the revelation as it tasted. That is why there are only a few variations in their interpretation and they do not contradict each other in their meanings, but you make more extensive and broader. There is therefore no doubt regarding the recitation of the Quran. There is no doubt that the Prophet practiced these different modes of recitation in the few variants that exist today, and they also make broader meanings.
As examples consider the two interpretations of authentic
a) verse 3 of Surah “Al Fatiha (Opening)
b) verse 6 of Surah “Al Maida-(The Table).
A reading of “Al Fatiha” (openness), marrow, Sura 1, verse 3 is:
That means — The Lord of the Day of Judgement “and the other is:
This interpretation means “The Master of the Day of Judgement.”
Obviously, both interpretations make the whole meaning of the verse clearer.
An interpretation of Surah 5 verse 6 is:
Means – “Lavad your faces … and (Lavad) your feet” as in the time of ablution barefoot.
The second interpretation is:
Means – “Lavad your faces and rinse your heads and (wash) your feet — with wet hands. The second interpretation refers to the washing of the feet, keeping socks whenever a previous full ablution.
This concession is valid for 24 hours at home and for seventy-two standard hours of travel. It is obvious that the different interpretations of these two examples, there is no essential contradiction at all. Moreover, they make the whole meaning wider. And the same goes for all other variants of interpretation.
