They want to extinguish the light of Allah with their mouths, but (9:32)

﴿يُرِيدُونَ أَن يُطْفِئُوا نُورَ اللَّهِ بِأَفْوَاهِهِمْ وَيَأْبَى اللَّهُ إِلَّا أَن يُتِمَّ نُورَهُ وَلَوْ كَرِهَ الْكَافِرُونَ﴾
[ التوبة: 32]

9:32 They want to extinguish the light of Allah with their mouths, but Allah refuses except to perfect His light, although the disbelievers dislike it.

The disbelievers from all the various religious groups who disbelieve by making up wrong beliefs and rejecting Muhammad ( peace and blessings be upon him ), wish to eradicate Islam.
So they undermine the clear proofs establishing that there is only one God and that His Messenger has brought the truth.
However, Allah will not allow anything to stop His sacred path being perfected and being made clear.
He will raise His Religion above everything else, even if the disbelievers hate that, and if Allah wills something, others are powerless to prevent it.

They (the disbelievers, the Jews and the Christians) want to extinguish Allah's Light (with which Muhammad SAW has been sent - Islamic Monotheism) with their mouths, but Allah will not allow except that His Light should be perfected even though the Kafirun (disbelievers) hate (it).
