It was narrated from Abu Hurairah:

"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.

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنِ ابْنِ أُكَيْمَةَ اللَّيْثِيِّ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ انْصَرَفَ مِنْ صَلاَةٍ جَهَرَ فِيهَا بِالْقِرَاءَةِ فَقَالَ " هَلْ قَرَأَ مَعِي أَحَدٌ مِنْكُمْ آنِفًا " . قَالَ رَجُلٌ نَعَمْ يَا رَسُولَ اللَّهِ . قَالَ " إِنِّي أَقُولُ مَا لِي أُنَازَعُ الْقُرْآنَ " . قَالَ فَانْتَهَى النَّاسُ عَنِ الْقِرَاءَةِ فِيمَا جَهَرَ فِيهِ رَسُولُ اللَّهِ ﷺ بِالْقِرَاءَةِ مِنَ الصَّلاَةِ حِينَ سَمِعُوا ذَلِكَ .
