FAQ13: The Quran was not revealed to the Prophet (saww) in this world, rather it was revealed to him in some other realm before anything else was created. Therefore whenever Allah (swt) says to the Prophet (saww) about any incident that “you did not know this”, or “ you were not aware of this” then He (swt) is talking about that realm, not this world.
There is no proof for claiming that the Quran was not revealed in this world rather in some other realm before the creation of everything. We challenge anyone to bring such a proof

This can also be refuted through the Quran itself.
Before the Battale of Tabuk, some hypocrites came to the Prophet (saww) to ask for permission to stay behind and not participate in the battle, so the Prophet (saww) gave them permission, so Allah (swt) revealed the verse (9:43):
May Allah pardon you, [O Muhammad]; why did you give them permission [to remain behind]? [You should not have] until it was evident to you who were truthful and you knew [who were] the liars.
First of all, this proves that the Prophet (saww) did not know who the liars among them were and who the truthful ones were.
Secondly, if we assume, as the questioner says, that the Quran was revealed to the Prophet (saww) before he even came to this world, then how is it possible that the Prophet (saww) already knew about the above verse, and hence knew that he should not give permission to the hypocrites to stay behind, yet when the time came he gave permission to the hypocrites without ascertaining who were truthful and who were liars.
This and many other such examples in the Quran, prove that the claim that the Quran was revealed to the Prophet (saww) before he even came to this world is a lie and anti Quranic.
