41:26
وَ قَالَ ٱلَّذِينَ كَفَرُ وا۟ لَا تَسْمَعُ وا۟ لِ هَٰذَا ٱلْ قُرْءَانِ وَ ٱلْغَ وْا۟ فِي هِ لَعَلَّ كُمْ تَغْلِبُ ونَ
And those who disbelieve say, "Do not listen to this Qur'an and speak noisily during [the recitation of] it that perhaps you will overcome."
88:11
لَّا تَسْمَعُ فِي هَا لَٰغِيَةً
Wherein they will hear no unsuitable speech.
