لَيْسَ بِمَخْلُوقٍ كَكَلَامِ الْبَرِيَّةِ
It is not created like the speech of creatures.
Divine speech is not measured by the form or manner of creaturely speaking. Allah’s attribute of speech is affirmed in a way befitting Him.
The Qur’an is held to be truly Allah’s speech and not equivalent to the speech of created beings.
