It is narrated from Sayyiduna Abu Ruh that once the Prophet (peace be upon him) led us in a prayer in which he recited Surah Ar-Rum. During the recitation, some confusion occurred to him. After the prayer, the Prophet (peace be upon him) said that Satan caused us confusion during the recitation because of those people who come to prayer without ablution. Therefore, when you come for prayer, perform ablution thoroughly.
