Bukti Qur'an ditulis di jaman Nabi SAW

The Qur'an was written down in part during its revelations from
pieces of papyrus, flat stones, palm leaves, pieces of leather,
wooden boards, and the heart of the believers men and women
(memorization) even in the time of the Prophet (s.a.w). Here are some
evidences:

1. The well-known report about Umar bin Khattab's (r.a) conversion to
Islam shows that large passages of the Qur'an had already been
written down even at the early time, in Mecca, long before the hijra,
when the Prophet was still in the house of Arqam (one of the first
converts in Islam). It was surah Taha (chapter 20) of the Qur'an
which Umar read in the sheet of his sister that brought him to Islam.
[ref: Ibn Hisham, pp.156-157]


2. The Qur'an was not only written down by those Companions who did
so on their initiative. Indeed, the Prophet, when a revelation came,
called for the scribe and dictated to him, as mentioned in the hadith:

When surah 4 verse 95 of the Qur'an was revealed, the Prophet
said: "Call Zaid for me, let him bring the board, the ink pot,
and the scapula bones." Then he said: "Write: 'Not equal are
those believers...' (4:95)
[ref: Bukhari, VI, No.512; also VI, No.116-118]


3. It was also reported that material upon which the revelation had
been written down was kept in the house of the Prophet.
[ref: As-Suyuti, Itqan, I, p.58]


4. Another report informs us that when people came to Madina to learn
about Islam in the time of the Prophet, they were provided with
copies of the chapters of the Qur'an, to read and learn them by heart.
[ref: Hamidullah M., Sahifa Hammam ibn Munabbih, p.64]


5. The Prophet sent copies of the chapters of the Qur'an with some
Muslims for instruction in Islam of the people of Yemen.
[ref: Muwatta' Imam Malik, p.204]


6. The Qur'an did exist as a written document in the life time of the
Prophet (s.a.w), as mentioned in the following ahadith:

He (s.a.w) 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."
- i.e. the enemy may seize it and may quarrel with you over it -.
[ref: Muslim, III, No.4607,4608,4609; Bukhari, IV, No.233]


Ibn Umar said: No doubt the Prophet and his Companions travelled
in the land of the enemy and they knew the Qur'an then. - i.e. they
knew that the Qur'an was carried, as a scripture, by
the Muslims - [ref: Bukhari, Ch.129]


The Qur'an had been WRITTEN DOWN in its entirety in the time of the
Prophet. No knowledagble scholars have ever doubted this clear fact.
