The Quraan is the revealed words of Allaah, uncreated, from Him it began and unto Him it will return.
"…because the Quraan is from the Speech of Allaah and the speech of Allaah is an Atrribute amongst His Attributes and His Attributes are uncreated…"
The meaning of "from Him it began," is that Allaah Spoke it intially. The meaning of "and unto Him it will return," means that it will return to Allaah at the end of time by being uplifted from the books and hearts as an honor to it due to the people taking it as a sort of play and jest.
