سَأَلْتُ أَبَا عَبْدِ اللَّهِ ع عَنِ الرَّجُلِ أَمَّ قَوْماً وَ هُوَ عَلَى غَيْرِ طُهْرٍ فَأَعْلَمَهُمْ بَعْدَ مَا صَلَّوْا فَقَالَ يُعِيدُ هُوَ وَ لَا يُعِيدُونَ.
“I once asked abu ’Abd Allah (a.s.), about a man who leads a people in Salah (prayer) but does not have a valid Wudu’ and informs them after Salah (prayer). He (the Imam) said, ‘Only he, but not they, must perform again.”’
