Wants a proof that Quran is God's word !!

There are two versions of the story of the first revelation. In the Sirat Rasul Allah by Ibn Ishaq it goes as follows:

When it was the night on which God honored him with his mission and showed mercy on His servants thereby, Gabriel brought him the command of God. "He came to me," said the apostle of God, "while I was asleep, with a coverlet of brocade whereon was some writing, and said, ‘Read!’ I said, ‘What shall I read?’ (وما اقر�£ [10]) He pressed me with it so tightly that I thought it was death; then he let me go and said, ‘Read!’ I said, ‘What shall I read?’ He pressed me with it again so that I thought it was death; then he let me go and said ‘Read!’ I said, ‘What shall I read?’ He pressed me with it the third time so that I thought it was death and said ‘Read!’ I said, ‘What then shall I read?’—and this I said only to deliver myself from him, lest he should do the same to me again. He said:

‘Read in the name of thy Lord who created, Who created man of blood coagulated. Read! Thy Lord is the most beneficent, Who taught by the pen, Taught that which they knew not unto men.’

So I read it, and he departed from me. And I awoke from my sleep, and it was as though these words were written on my heart.
Sirat Rasul Allah by Ibn Ishaq [11]
It says وما اقر�£ "and what (should I) read?". So in this story Muhammad can read, he just asks what should he read.

Ibn Ishaq died in 761. But in 810 was born Bukhari, who wrote a little different story in his Sahih Bukhari collection:

He used to take with him the journey food for the stay and then come back to (his wife) Khadija to take his food likewise again till suddenly the Truth descended upon him while he was in the cave of Hira. The angel came to him and asked him to read. The Prophet (ﷺ) replied, "I do not know how to read. (مَا �£َنَا بِقَارِئٍ)" The Prophet (ﷺ) added, "The angel caught me (forcefully) and pressed me so hard that I could not bear it any more. He then released me and again asked me to read and I replied, 'I do not know how to read.' Thereupon he caught me again and pressed me a second time till I could not bear it any more. He then released me and again asked me to read but again I replied, 'I do not know how to read (or what shall I read)?' Thereupon he caught me for the third time and pressed me, and then released me and said, 'Read in the name of your Lord, who has created (all that exists), created man from a clot. Read! And your Lord is the Most Generous." (96.1, 96.2, 96.3)


Sahih Bukhari 1:1:3
If the iqra in 96:1 meant "recite" as some translators translated it, then here Muhammad says "I don't know how to recite".
This shift from "and what shall I read" (وما اقر�£) to "I don't know how to read" (مَا �£َنَا بِقَارِئٍ) seems to indicate that Muhammad's illiteracy was a later invention.

@Miaw The group in your link are called 'Hadith rejectors'.

Shia do not strictly follow Hadith, and I would not minimize them by dismissively classifying them as " Hadith rejectors".
