Yes. The Holy Qur'an repeatedly proclaims that it is divine.
'(This is) the revelation of the Book in which there is no doubt, from the Lord of the Worlds.' (32:2).
'Verily this is a Revelation from the Lord of the Worlds' (26:192).
'(It is a Revelation) sent down by (Him), the Exalted in Might, Most Merciful' (36:5).
