وَقَالَ ٱلَّذِينَ كَفَرُواْ لَا تَسۡمَعُواْ لِهَٰذَا ٱلۡقُرۡءَانِ وَٱلۡغَوۡاْ فِيهِ لَعَلَّكُمۡ تَغۡلِبُونَ ٢٦
And those who disbelieve say, "Do not listen to this Qur’ān and speak noisily1 during [the recitation of] it that perhaps you will overcome."
Translation: Saheeh International (English)
1 Other meanings include "speak improperly" and/or "make a clamor." The purpose of this was to prevent the hearing or understanding of the Qur’ān.
Each word's meaning and sound
When they became helpless in countering evidence with evidence, the disbelievers said, urging one another, “Do not listen to this Qur’ān that Muhammad recites to you and do not submit to it, rather, shout and raise your voices when he recites it to you so that perhaps you can gain the upper hand over him and he stops reciting and calling towards it, then we will be relieved of him.”
