Ramai pelajar Muqaddam saya yang bertanya mengenai "bukti kesahihan Al-Quran" atau "bukti keaslian Al-Quran". Berikut adalah bukti bahawa Al-Quran adalah ASLI:
RECORDING AND PRESERVATION OF THE QUR'AN
The very first word revealed to Muhammad (pbuh) was 'iqra' meaning read or recite (Surah 96 Ayah 1). Thus it is not surprising that as soon as a verse was revealed, he would memorize it so that he could recite it to others, and the very next Surah that was revealed was Surah 68 Ayah (1-2), which emphasised the use of pen, thus not only that the revealed verses were memorized, they were also put in writing.
"Nuun. By the Pen and by the (Record) which (men) write." (68:1)
"Thou art not by the grace of thy Lord mad or possessed." (68:2)
Among the many companions of the Prophet, some of the most literate, who had good command of the Arabic language, were Abu-Bakr, Ali Ibn Abi-Talib, Othman Ibn Afan, Zaid Ibn Thabit, Umar Ibn Alkhattab. There were many companions towards the end of this mission, some were more closer to the Prophet than others. They were all very pious and righteous people, full of integrity and honesty. They were ready to follow and support the Prophet at the expense of all their personal belongings and lives. In addition to acting as his scribes, they also memorized the Qur'an directly from Muhammad (pbuh).
As soon as a portion of the Qur'an was revealed, Muhammad would call his scribe, from among his companions, to record it in writing. The Prophet would than ask the scribe to read the portion to ensure that what was written down was verbatim word of Allah. Once satisfied with the written text, the Prophet would instruct the scribe to put the verse or verses where they belonged. That is, he would say the name of the Surah and the location where the just revealed portion (verse or verses) were to be inserted, thus ensuring that the textual order of the Qur'an was in accordance with the Divine plan.
His scribes used leather, parchments, leaves and tablets to write down the verses. These manuscripts were kept in the safe custody, and it is reported that in fact they were kept in the house of the Prophet.
It was quite common for many companions to also make their own personal copies with marginal notes, foot-notes and comments for their personal use. Thus the Qur'anic verses were not only memorized by the Prophet and many of his companions, but also existed in written form during the lifetime of the Prophet, unlike any other scriptures in the history of world religion.
In order to ensure the authenticity of the Qur'an, Allah Almighty took the necessary steps - once every year during the month of Ramadan, Angel Gabriel would come to the Prophet and hear him recite the Qur'an (whatever was revealed to that point in time). And during the last year, before Muhammad's death, Angel Gabriel came twice to hear him recite the Qur'an, thus ensuring that the words of Allah have not been forgotten or changed. During this review many companions were present and heard the Prophet's recital. Hence, they also had the chance to ensure that what they had memorized were correct and not forgotten.
We also know that the Prophet lead the five daily prayers, during which he would recite portions of the Qur'an. This also became an excellent means of ensuring that his followers would never forget what they had memorized.
Muhammad (pbuh) was the 'Living Qur'an'. He helped his companions memorize the Qur'an and as time went by, many of those who embraced Islam, started memorizing as well. These memorizers of the Qur'an, known as Huffaz-Al-Qur'an. Thus, the Qur'an was in the memory of many Muslims and was also in written form during the lifetime of the Prophet. The proof that Qur'an was in written form during the lifetime of the Prophet is evident from the following Hadith:
Narrated Ibn Umar: "The messenger of Allah (pbuh) Said: Do not take the Qur'an on a journey with you, for I am afraid lest it should fall into the hands of the enemy". (Ref: Bukhari, Vol. IV No. 233)
Another strong evidence that the revelations were in written form during the lifetime of the Prophet comes from his last sermon - The Prophet is reported to have said:
"I leave behind me two things, the Qur'an and my examples the Sunnah and if you follow these you will never go astray'........
If the Qur'an was not in written form during the lifetime of the Prophet, he would never have said I leave behind the Qur'an.
Hence, unlike any other scripture, the Qur'anic revelations were recorded and written down during the lifetime of The Prophet (Muhammad, PBUH).
Nota: Sehingga hari ini ramai orang islam yang hafal Al-Quran sehinggakan kanak-kanak pun boleh menghafal Quran.
