[Machine] The Messenger of Allah ﷺ prayed with us in the morning and the recitation became difficult for him. When the Messenger of Allah ﷺ finished his prayer, he turned towards us and said, "I see you reciting behind your imam when he raises his voice." We said, "Yes, indeed, O Messenger of Allah." He said, "Do not do so, except when you recite with Umm al-Qur'an (Surah Al-Fatiha), for there is no prayer for the one who does not recite it."
صَلَّى بِنَا رَسُولُ اللهِ ﷺ الصُّبْحَ فَثَقُلَتْ عَلَيْهِ الْقِرَاءَةُ فَلَمَّا انْصَرَفَ رَسُولُ اللهِ ﷺ مِنْ صَلَاتِهِ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ إِنِّي لَأَرَاكُمْ تَقْرَءُونَ خَلْفَ إِمَامِكُمْ إِذَا جَهَرَ قَالَ قُلْنَا أَجَلْ وَاللهِ يَا رَسُولَ اللهِ هَذَا قَالَ فَلَا تَفْعَلُوا إِلَّا بِأُمِّ الْقُرْآنِ؛ فَإِنَّهُ لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِهَا
