It was narrated from Shabib Abi Rawh, from a man among the companions of the Prophet (ﷺ), that:
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.'"
