وَعَن شبيب بن أبي روح عَنْ رَجُلٍ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَّى صَلَاةَ الصُّبْحِ فَقَرَأَ الرُّومَ فَالْتَبَسَ عَلَيْهِ فَلَمَّا صَلَّى قَالَ: «مَا بَالُ أَقْوَامٍ يُصَلُّونَ مَعَنَا لَا يُحْسِنُونَ الطَّهُورَ فَإِنَّمَا يلبس علينا الْقُرْآن أُولَئِكَ» . رَوَاهُ النَّسَائِيّ

Shabib b. Abu Rauh reported on the authority of one of the companions of God’s messenger that God’s messenger prayed the morning prayer and recited Ar-Rum*, but became confused about it. When he finished the prayer he said, “What is the matter with people who pray along with us without performing the purification properly? It is only those who cause us confusion about the Qur’an.” *Qur’an, xxx. Nasa’i transmitted it.
