Qur’onning yetti xil lahjada nozil bo‘lishi uni turli qabilalar uchun o‘qish va yodlashni ancha osonlashtirdi. Masalan, “ ‘alayhim” (ularning ustiga) so‘zini ba’zilar “ ‘alayhumoo” deb o‘qidilar, “siraat” (yo‘l, ko‘prik) so‘zini ba’zilar “siraat” deb, boshqalar esa “ziraat” deb o‘qidilar, “mu’min” (imonli) so‘zi ham “moomin” deb o‘qilgan. Natijada Payg‘ambar ﷺ hayot ekanlarida ham Payg‘ambarning ko‘plab izdoshlari Qur’onning katta qismlarini yod ola oldilar. Arablarning aksariyati o‘qishni ham, yozishni ham bilmagani va Qur’onning ko‘p qismi Payg‘ambar ﷺ hayotlik vaqtida yodlash orqali saqlangani sababli, uning yodlanishini osonlashtirgan har bir omil juda muhim edi. Shunday ekan, Qur’onning yetti shaklda nozil bo‘lishi uning haqiqiy saqlanishida muhim rol o‘ynagan, deyish mumkin. Shuni ham ta’kidlash lozimki, Payg‘ambar ﷺ vafotlaridan keyin Qur’onni jamlash jarayonida, Payg‘ambar ﷺ hayotlik davrida yozilgan narsalarning to‘g‘riligini tekshirishning yagona yo‘li ularni yodda saqlanganlar bilan solishtirish edi. Shu sababli, uni yodlay oladigan kishilar qancha ko‘p bo‘lsa, Qur’on shuncha aniq jamlanib, tekshirilishi mumkin edi. Demak, yodlashning osonligi Qur’onni aniq jamlashda ham hal qiluvchi rol o‘ynagan.

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.
