وَإِذَا قُرِئَ الْقُرْآنُ فَاسْتَمِعُواْ لَهُ وَأَنصِتُواْ لَعَلَّكُمْ تُرْحَمُونَ
[7:204]
And when the Quran is recited, then listen to it and remain silent, that mercy may be shown to you.
When the Qur'an is read, listen to it with attention, and hold your peace: that ye may receive Mercy.
And when the Qur'an is recited, give ear to it and pay heed, that ye may obtain mercy.
