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
