"The Messenger of Allah ﷺ led us in one of the prayers in which the recitation is done out loud, and he said: 'None of you should recite when I recite out loud, apart from the Umm Al_quran (Al Fatihah).'"  

صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ بَعْضَ الصَّلَوَاتِ الَّتِي يُجْهَرُ فِيهَا بِالْقِرَاءَةِ فَقَالَ لاَ يَقْرَأَنَّ أَحَدٌ مِنْكُمْ إِذَا جَهَرْتُ بِالْقِرَاءَةِ إِلاَّ بِأُمِّ الْقُرْآنِ
