ذِكْرُ كَرَاهِيَةِ رَفْعِ الصَّوْتِ لِلْمَأْمُومِ بِالْقِرَاءَةِ لِئَلَّا يُنَازِعُ الْإِمَامُ مَا يَقْرَؤُهُ
"The Messenger of Allah ﷺ finished a prayer in which he recited out loud, then he said: 'Did any one of you recite with me just now?' A man said: 'Yes, O Messenger of Allah.' He said: 'I was wondering what was distracting me in reciting Quran.'" So the people stopped reciting in prayers in which the Messenger of Allah ﷺ recited out loud when they heard that. (Using translation from Nasāʾī 919)
أَنَّ رَسُولَ اللَّهِ ﷺ انْصَرَفَ مِنْ صَلَاةٍ جَهَرَ فِيهَا بِالْقِرَاءَةِ فَقَالَ «هَلْ قَرَأَ أَحَدٌ مِنْكُمْ آنِفًا؟ » فَقَالَ رَجُلٌ نَعَمْ أَنَا يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ ﷺ «إِنِّي أَقُولُ مَا لِي أُنَازَعُ الْقُرْآنَ؟ » فَانْتَهَى النَّاسُ عَنِ الْقِرَاءَةِ فِيمَا جَهَرَ فِيهِ رَسُولُ اللَّهِ ﷺ حِينَ سَمِعُوا ذَلِكَ مِنْ رَسُولِ اللَّهِ ﷺ
