﴿ وَإِذَا قُرِئَ ٱلْقُرْءَانُ فَٱسْتَمِعُوا۟ لَهُۥ وَأَنصِتُوا۟ لَعَلَّكُمْ تُرْحَمُونَ ﴾

“Hence, when the Qur'an is voiced, hearken unto it, and listen in silence, so that you might be graced with [God's] 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.
