quran:7:204 –

So when the Qur'an is recited, then listen to it and pay attention that you may receive mercy.  

And when the Qur’ān is recited, listen to it and pay heed, ˹refraining˺ from speech, so that you might find mercy: this was revealed regarding ˹the requirement of˺ refraining from speech during the ˹mosque˺ sermon, which here has been expressed by ˹the recital of˺ ‘the Qur’ān’, because it ˹the sermon˺ comprises it; others say that it was revealed regarding the ˹requirement of silence and attention during the˺ recitation of the Qur’ān in general.
القرآن:٧:٢٠٤ –

وَإِذَا قُرِئَ الْقُرْآنُ فَاسْتَمِعُوا لَهُ وَأَنْصِتُوا لَعَلَّكُمْ تُرْحَمُونَ  

{وإذا قُرئ القرآن فاستمعوا له وأنصتوا} عن الكلام {لعلكم ترحمون} نزلت في ترك الكلام في الخطبة وعبَّر عنها بالقرآن لاشتمالها عليه، وقيل في قراءة القرآن مطلقا.
