We were behind the Messenger of Allah ﷺ at the dawn prayer, and he recited (the passage), but the recitation became difficult for him. Then when he finished, he said: Perhaps you recite behind your imam? We replied: Yes, it is so, Messenger of Allah. He said: Do not do so except when it is Fatihat al-Kitab, for he who does not recite it is not credited with having prayed.  

كُنَّا خَلْفَ رَسُولِ اللَّهِ ﷺ فِي صَلاَةِ الْفَجْرِ فَقَرَأَ رَسُولُ اللَّهِ ﷺ فَثَقُلَتْ عَلَيْهِ الْقِرَاءَةُ فَلَمَّا فَرَغَ قَالَ لَعَلَّكُمْ تَقْرَءُونَ خَلْفَ إِمَامِكُمْ قُلْنَا نَعَمْ هَذَا يَا رَسُولَ اللَّهِ قَالَ لاَ تَفْعَلُوا إِلاَّ بِفَاتِحَةِ الْكِتَابِ فَإِنَّهُ لاَ صَلاَةَ لِمَنْ لَمْ يَقْرَأْ بِهَا  

"Messenger of Allah prayed the Subh prayer, and he had difficulty with the recitation. When turned (after finishing) he said: 'I think that you are reciting behind your Imam?'" He said: "We said: 'Yes, Messenger of Allah, by Allah!' He said: 'Do not do that, except for Umm Al-Kitab, for there is no Salat for one who does not recite it.'" (Using translation from Tirmidhī 311)   

صَلَّى بِنَا رَسُولُ اللهِ ﷺ صَلَاةَ الْغَدَاةِ فَثَقُلَتْ عَلَيْهِ الْقِرَاءَةُ فَلَمَّا انْصَرَفَ قَالَ إِنِّي لَأَرَاكُمْ تَقْرَءُونَ وَرَاءَ إِمَامِكُمْ قُلْنَا نَعَمْ وَاللهِ يَا رَسُولَ اللهِ إِنَّا لَنَفْعَلُ هَذَا قَالَ فَلَا تَفْعَلُوا إِلَّا بِأُمِّ الْقُرْآنِ؛ فَإِنَّهُ لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِهَا  

[Machine] The Messenger of Allah ﷺ prayed Fajr prayer with us, and recitation became heavy for him during it. When the Messenger of Allah ﷺ finished his prayer, he turned towards us with his face and said, "I see you reciting behind your imam when he recites aloud." We replied, "Yes, indeed, O Messenger of Allah, this is what we do." The Messenger of Allah ﷺ said, "Do not do so except with the Mother of the Quran, for there is no prayer for the one who does not recite it."  

صَلَّى بِنَا رَسُولُ اللهِ ﷺ الصُّبْحَ فَثَقُلَتْ عَلَيْهِ فِيهَا الْقِرَاءَةُ فَلَمَّا انْصَرَفَ رَسُولُ اللهِ ﷺ مِنْ صَلَاتِهِ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ إِنِّي لَأَرَاكُمْ تَقْرَءُونَ خَلْفَإِمَامِكُمْ إِذَا جَهَرَ قَالَ قُلْنَا أَجَلْ (1 وَاللهِ يَا رَسُولَ اللهِ هَذَا 1) فَقَالَ رَسُولُ اللهِ ﷺ لَا تَفْعَلُوا إِلَّا بِأُمِّ الْقُرْآنِ؛ فَإِنَّهُ لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِهَا  

[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

[Machine] The Messenger of Allah ﷺ prayed Fajr with us, and the recitation became difficult for him. After finishing the prayer, he asked, "Did you recite behind me?" We replied, "Yes." He said, "Do not do so, except with the mother of the Book (meaning Al-Fatiha) because there is no prayer for the one who does not recite it."  

صَلَّى بِنَا رَسُولُ اللَّهِ ﷺ الْفَجْرَ فَثَقُلَتْ عَلَيْهِ الْقِرَاءَةُ فَلَمَّا سَلَّمَ قَالَ «تَقْرَءُونَ خَلْفِي؟ » قُلْنَا نَعَمْ قَالَ «فَلَا تَفْعَلُوا إِلَّا بِأُمِّ الْكِتَابِ فَإِنَّهُ لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِهَا»

"إِنِّى أَرَاكُمْ تقرءُونَ وراءَ إِمامكُم فلا تفْعلوا إِلَّا بأُمِّ القُرْآن فإنَّه لا صلاةَ لمنْ لمْ يَقْرأْ بها" .
