﴿ يُرِيدُونَ أَن يُطْفِـُٔوا۟ نُورَ ٱللَّهِ بِأَفْوَٰهِهِمْ وَيَأْبَى ٱللَّهُ إِلَّآ أَن يُتِمَّ نُورَهُۥ وَلَوْ كَرِهَ ٱلْكَٰفِرُونَ ﴾

“They want to extinguish God's [guiding] light with their utterances: but God will not allow [this to pass], for He has willed to spread His light in all its fullness, however hateful this may be to all who deny the truth.”

They desire to extinguish God’s light His Law and His proofs with their tongues with what they say about Him; and God refuses but to perfect to make manifest His light even though the disbelievers be averse to this.
