He prayed Subh and recited Ar-Rum, but he stumbled in his recitation. When he had finished praying he said: 'What is the matter with people who pray with us without purifying themselves properly? Those people make us stumble in reciting Quran.'"  

عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى صَلاَةَ الصُّبْحِ فَقَرَأَ الرُّومَ فَالْتَبَسَ عَلَيْهِ فَلَمَّا صَلَّى قَالَ مَا بَالُ أَقْوَامٍ يُصَلُّونَ مَعَنَا لاَ يُحْسِنُونَ الطُّهُورَ فَإِنَّمَا يَلْبِسُ عَلَيْنَا الْقُرْآنَ أُولَئِكَ  

[Machine] "On the authority of a man from the Companions of the Prophet ﷺ who said, the Messenger of Allah ﷺ prayed the Fajr prayer and recited Surah Ar-Rum (Chapter of the Romans) in it. He became confused in his recitation. After the prayer, he said, "What is the matter with the men who join us in prayer without being in a state of purity? Those are the ones who spoil our prayer. Whoever prays with us, let him perfect his purification."  

عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ قَالَ صَلَّى رَسُولُ اللهِ ﷺ الْفَجْرَ فَقَرَأَ فِيهِمَا بِالرُّومِ فَالْتُبِسَ عَلَيْهِ فِي الْقِرَاءَةِ فَلَمَّا صَلَّى قَالَ مَا بَالُ رِجَالٍ يَحْضُرُونَ مَعَنَا الصَّلَاةَ بِغَيْرِ طُهُورٍ أُولَئِكَ الَّذِينَ يَلْبِسُونَ عَلَيْنَا صَلَاتَنَا مَنْ شَهِدَ مَعَنَا الصَّلَاةَ فَلْيُحْسِنِ الطُّهُورَ  

He prayed Subh and recited Ar-Rum, but he stumbled in his recitation. When he had finished praying he said: 'What is the matter with people who pray with us without purifying themselves properly? Those people make us stumble in reciting Quran.'" (Using translation from Nasāʾī 947)  

عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ عَنِ النَّبِيِّ ﷺ أَنَّهُ صَلَّى صَلَاةَ الصُّبْحِ فَقَرَأَ الرُّومَ وَالْتُبِسَ عَلَيْهِ فَلَمَّا صَلَّى قَالَ «مَا بَالُ أَقْوَامٍ يُصَلُّونَ مَعَنَا لَا يُحْسِنُونَ الطُّهُورَ فَإِنَّمَا يَلْبِسُ عَلَيْنَا الْقُرْآنَ أُولَئِكَ»  

"عَنْ أَبَي رُوحٍ، عَنْ رَجُلٍ مِنْ أَصْحَاب مُحمدِ ﷺ قَالَ: صَلَّى النَّبِيُّ ﷺ صَلَاة الَفْجرِ فَقَرأَ بِالرُّومِ فَألبسَ عَلَيْهِ، فَلَمَّا انْصَرفَ قَالَ: مَا بالُ أَقَوام يُصَلُّونَ الصَّلاةَ مَعَنَا بِغَيرِ طهور، مَنْ صَلَّى مَعَنَا فَلْيُحسِنْ وضُوءَهُ، وَفِي لَفْظٍ إِنَّمَا يَردد طهوركُم".
