Chapter: Moderation When Reciting Qur'an In A Prayer When It Is To Be Recited Out Loud, And Making it Neither Too Loud Nor Too Soft, And When There Is The Fear Of Negative Consequences If It Is Recited Out Loud
Ibn 'Abbas reported: The word of (Allah) Great and Glorious: 'And utter not thy prayer loudly, nor be low in it" (xvii. 110) was revealed as the Messenger of Allah (ﷺ) was hiding himself in Makkah. When he led his Companions in prayer he raised his voice (while reciting the) Qur'an. And when the polytheists heard that, they reviled the Qur'an and Him Who revealed it and him who brought it. Upon this Allah, the Exalted, said to His Apostle (ﷺ) : Utter not thy prayer so loudly that the polytheists may hear thy recitation and (recite it) not so low that it may be inaudible to your Companions. Make them hear the Qur'an, but do not recite it loudly and seek a (middle) way between these. Recite between loud and low tone.
'A'isha reported that so far as these words of (Allah) Glorious and High are concerned:" And utter not thy prayer loudly, not be low in it" (xvii. 110) relate to supplication (du'a').
