Surah As-Saf (The Solid Ranks), Verse 8

یُرِیْدُوْنَ لِیُطْفِـُٔوْا نُوْرَ اللّٰهِ بِاَفْوَاهِهِمْ وَاللّٰهُ مُتِمُّ نُوْرِهٖ وَلَوْ كَرِهَ الْكٰفِرُوْنَ ۟

Yureedoona liyutfi'oo nooral laahi bi afwaahihim wallaahu mutimmu noorihee wa law karihal kaafiroon

“Their intention is to extinguish Allah's Light (by blowing) with their mouths: But Allah will complete (the revelation of) His Light, even though the Unbelievers may detest (it).”
