Wahyu al-Qur'an dalam tujuh dialek yang berbeza memudahkan bacaan dan hafalannya bagi pelbagai qabilah. Sebagai contoh, frasa "‘alayhim" (ke atas mereka) dibaca oleh sesetengah orang sebagai "‘alayhumoo", perkataan "siraat" (jalan, titian) dibaca oleh sesetengah orang sebagai "siraat" dan oleh yang lain sebagai "ziraat", dan perkataan "mu’min" (orang beriman) juga dibaca sebagai "moomin". Akibatnya, bilangan pengikut Nabi ﷺ yang dapat menghafal bahagian-bahagian besar al-Qur'an semakin ramai ketika Nabi ﷺ masih hidup. Oleh kerana kebanyakan orang Arab tidak dapat membaca mahupun menulis, dan sebahagian besar al-Qur'an dipelihara semasa hayat Nabi ﷺ melalui hafalan, sebarang faktor yang memudahkan hafalan adalah sangat penting. Maka, dapat dikatakan bahawa wahyu al-Qur'an dalam tujuh bentuk memainkan peranan penting dalam pemeliharaan sebenar al-Qur'an. Perlu juga diperhatikan bahawa semasa pengumpulan al-Qur'an selepas kewafatan Nabi ﷺ, satu-satunya cara untuk mengesahkan ketepatan apa yang telah ditulis daripada al-Qur'an semasa hayat Nabi ﷺ ialah dengan membandingkannya dengan apa yang telah dihafal. Oleh itu, semakin ramai orang yang mampu menghafalnya, semakin tepat ia dapat dikumpulkan dan disahkan. Akhirnya, kemudahan dalam hafalan juga memainkan peranan utama dalam pengumpulan al-Qur'an dengan tepat.

The revelation of the Qur’aan in seven different dialects made its recitation and memorization much easier for the various tribes. For example, the phrase, “ ‘alayhim” (on them), was read by some as “ ‘alayhumoo,” and the word “ siraat” (path, bridge), was read by some as “ siraat” and by others as “ ziraat,” and the word “mu’min” (believer) was also read as “moomin.” As a result, a greater number of the Prophet’s followers were able to memorize large portions of the Qur’aan while the Prophet (ﷺ) was still alive. Since the majority of the Arabs could neither read nor write and most of the Qur’aan was preserved during the Prophet’s lifetime by memorization, any factor which eased its memorization was of great importance. Hence, it could be said that the revelation of the Qur’aan in seven forms played a vital role in the actual preservation of the Qur’aan. It should also be noted that during the compilation of the Qur’aan after the Prophet’s death, the only means of verifying the correctness of what had been written of the Qur’aan during the Prophet’s lifetime was by comparing it with what had been memorized. Hence, the more people who were able to memorize it, the more accurately it could be compiled and verified. Consequently, the ease in memorization also played a key role in the accurate compilation of the Qur’aan.

Dalam banyak tempat di dalam al-Qur'an, Allah mencabar orang Arab pada zaman itu untuk menghasilkan satu surah yang serupa, walaupun yang paling pendek daripada surah-surahnya. Ketidakmampuan untuk meniru gaya al-Qur'an itu merupakan mukjizat yang membuktikan bahawa al-Qur'an pastilah daripada Allah. Mukjizat ini menjadi lebih jelas apabila tiada seorang pun daripada tujuh kabilah besar yang dapat meniru-nya, malah dalam dialek mereka sendiri, kerana tiada sesiapa yang boleh mendakwa bahawa ia sukar ditiru kerana tidak ditulis dalam dialek mereka.

In many places in the Qur’aan, Allaah challenged the Arabs of that time to produce a chapter similar to even its smallest chapter. The inability to imitate the Qur’aan’s style was a miracle which proved that the Qur’aan had to be from Allaah. This miracle became even more obvious when none of the seven major tribes could imitate it even in their own dialects, as no one could claim that it was difficult to imitate due to it not being in their own dialect
