After Allah mentioned that this Qur'an is a clear evidence, guidance and mercy for mankind, He commanded that one listen to the Qur'an when it is recited, in respect and honor of the Qur'an. This is to the contrary of the practice of the pagans of Quraysh, who said,

﴿لاَ تَسْمَعُواْ لِهَـذَا الْقُرْءَانِ وَالْغَوْاْ فِيهِ﴾

("Listen not to this Qur'an, and make noise in the midst of its (recitation)'') ﴿41:26﴾. Ibn Jarir reported that Ibn Mas`ud said; "We would give Salams to each other during Salah. So the Ayah of Qur'an was revealed;

﴿وَإِذَا قُرِىءَ الْقُرْءَانُ فَاسْتَمِعُواْ لَهُ﴾

(When the Qur'an is recited, then listen to it.)

﴿وَاذْكُر رَّبَّكَ فِي نَفْسِكَ تَضَرُّعًا وَخِيفَةً وَدُونَ الْجَهْرِ مِنَ الْقَوْلِ بِالْغُدُوِّ وَالاٌّصَالِ وَلاَ تَكُنْ مِّنَ الْغَـفِلِينَ - إِنَّ الَّذِينَ عِندَ رَبِّكَ لاَ يَسْتَكْبِرُونَ عَنْ عِبَادَتِهِ وَيُسَبِّحُونَهُ وَلَهُ يَسْجُدُونَ ﴾

(205. And remember your Lord within yourself, humbly and with fear and without loudness in words in the mornings and in the afternoons, and be not of those who are neglectful). (206. Surely, those who are with your Lord (angels) are never too proud to perform acts of worship to Him, but they glorify His praise and prostrate themselves before Him.)
