Faulty formulation: Since Allah is unlike creation, knowledge, hearing and sight should not be affirmed as His attributes.
Correct formulation: Incomparability does not mean negating the attributes that are affirmed for Allah. Those attributes are acknowledged without equating them with the limited, created attributes of humans.
لَيْسَ كَمِثْلِهِ شَيْءٌ وَهُوَ السَّمِيعُ الْبَصِيرُ
Nothing is like Him, and He is the All-Hearing, the All-Seeing.
The two parts belong together: neither resemblance nor negation of attributes is justified.
