Because early arabic language didn't have vowels and also some consonants had the same or almost the same form. New signs were introduced to seperate the different letters. But this still did not stop the different ways of reading.
In the first half of the fourth/tenth century the 'imaam of the Koran readers' in Baghdad, Ibn Moedjahid, gave a solution to this problem. He said that the word harf should be put equivalent to kira'a. He declared seven ways of reading correct. Because according to him the saying of the Prophet (PBUH) that the Koran was send in seven ahroef means that seven ways of reading are inspired.
Nowadays only to ways of reading are in use, Warsj of Nafi' and Hafs of 'Asim.
Could you tell me more about these different ways of reading? Are there ahadieth about this?.
Praise be to Allaah.
you should note, may Allaah bless you, that the Qur’aan was revealed in one style at the beginning, but the Messenger of Allaah (peace and blessings of Allaah be upon him) kept asking Jibreel until he taught him seven styles, all of which were complete. The evidence for that is the hadeeth of Ibn ‘Abbaas who narrated that the Prophet (peace and blessings of Allaah be upon him) said: “Jibreel taught me one style and I reviewed it until he taught me more, and I kept asking him for more and he gave me more until finally there were seven styles.”
(narrated by al-Bukhaari, 3047; Muslim, 819)
Secondly, what is meant by styles (ahruf, sing. harf)?
The best of the scholarly opinions concerning what is meant is that there are seven ways of reciting the Qur’aan, where the wording may differ but the meaning is the same; if there is a different meaning then it is by way of variations on a theme, not opposing and contradiction.
Some of the scholars said that what was meant by ahruf was the dialects of the Arabs, but this is far-fetched, because of the hadeeth of ‘Umar ibn al-Khattaab who said: “I heard Hishaam ibn Hakeem reciting Soorat al-Furqaan in a manner different from that in which I used to recite it and the way in which the Messenger of Allaah (peace and blessings of Allaah be upon him) taught me to recite it. I was about to argue with him whilst he was praying, but I waited until he finished his prayer, and then I tied his garment around his neck and seized him by it and brought him to the Messenger of Allaah (peace and blessings of Allaah be upon him) and said, ‘O Messenger of Allaah, I heard this man reciting Soorat-al-Furqaan in a way different to the way you taught it to me.’ The Messenger of Allaah (peace and blessings of Allaah be upon him) said to him, ‘Recite it,’ and he recited it as I had heard him recite it. The Messenger of Allaah (peace and blessings of Allaah be upon him) said, ‘It was revealed like this.’ Then he said to me, ‘Recite it,’ so I recited it and he said, ‘It was revealed like this.’ This Qur'aan has been revealed in seven different ways, so recite it in the way that is easiest for you.’”
(Narrated by al-Bukhaari, 2287; Muslim, 818)
It is known that Hishaam was Asadi Qurashi (i.e., from the clan of Bani Asad in Quraysh) and ‘Umar was ‘Adawi Qurashi (i.e., from the clan of Bani ‘Adiyy in Quraysh). Both of them were from Quraysh and Quraysh had only one dialect. If the difference in ahruf (styles) had been a difference in dialects, why would two men of Quraysh have been different?
The scholars mentioned nearly forty different opinions concerning this matter! Perhaps the most correct is that which we have mentioned above. And Allaah knows best.
It seems that the seven styles were revealed with different wordings, as indicated by the hadeeth of ‘Umar, because ‘Umar’s objection was to the style, not the meaning. The differences between these styles are not the matter of contradiction and opposition, rather they are synonymous, as Ibn Mas’ood said: “It is like one of you saying halumma, aqbil or ta’aal (all different ways of saying ‘Come here’).”
With regard to the seven recitations (al-qiraa’aat al-saba’), this number is not based on the Qur’aan and Sunnah, rather it is the ijtihaad of Ibn Mujaahid (may Allaah have mercy on him). People thought that al-ahruf al-saba’ (the seven styles) were al-qiraa’aat al-saba’ (the seven recitations) because they happened to be the same number. But this number may have come about coincidentally, or it may have been done deliberately by Ibn Mujaahid to match what was narrated about the number of styles (ahruf) being seven. Some people thought that the styles (ahruf) were the recitations, but this is a mistake. No such comment is known among the scholars. The seven recitations are one of the seven styles, and this is the style that ‘Uthmaan chose for all the Muslims.
When ‘Uthmaan made copies of the Qur’aan, he did so according to one style (harf), but he omitted the dots and vowel points so that some other styles could also be accommodated. So the Mus-haf that was copied in his time could be read according to other styles, and whatever styles were accommodated by the Mus-haf of ‘Uthmaan remained in use, and the styles that could not be accommodated fell into disuse. The people had started to criticize one another for reciting differently, so ‘Uthmaan united them by giving them one style of the Qur’aan.
Your saying that Mujaahid’s different recitations meant the seven styles (ahruf) is not correct, as was said by Shaykh al-Islam ibn Taymiyyah. (Majmoo’ah al-Fatawa, vol. 13, p. 210)
The seven readers or reciters were:
1- Naafi’ al-Madani
2- Ibn Katheer al-Makki
3- ‘Aasim al-Kufi
4- Hamzah al-Zayaat al-Kufi
5- Al-Kisaa’i al-Kufi
6- Abu ‘Amr ibn al-‘Ala’ al-Basri
7- ‘Abd-Allaah ibn ‘Aamir al-Shaami
The ones who have the strongest isnaad in recitation are Naafi’ and ‘Aasim.
The most eloquent are Abu ‘Amr and al-Kisaa’i.
Warsh and Qaaloon narrated from Naafi’.
Hafs and Shu’bah narrated from ‘Aasim.
And Allaah knows best.
Its the responsibility of every Moslem to learn Quran and tajweed and we also must teach our kids Quran and not only the Quran teaching we should let then be conscious of the basic of Islam and why it was reviled you bet it was railed and truth teaching of holy Quran and with tajweed we read Quran we can understand better all the responses that are demanded if we study koran from a qualified Quran tutor he will let you know verity core of Islam and why koran was reviled for it we should gain the information of the Scripture with there translation and the context of when those verses were reviled and why and that is only potential when we keep on with not simply learning quran for beginners but gaining the ability of Quran tafseer and one inquiry that we all is necessary to ask our self that why we all are here in the world to do good acts or to do bad acts to promote correct or to promote incorrect and will we be answerable to any one after this life of not then the interrogation remains the exact same that the reasons why we are here in the world but if yes then whom we have to reply is there any Lord All these reply exist when we go deep in to the Quran education do Quran reading and the so let us unite hands to full fill our task. We all must do quran memorization and listen to quran online when ever we have time to stay in touch
