قَالَ أَمِيرُ الْمُؤْمِنِينَ ص لَا يَؤُمُّ الْمُقَيَّدُ الْمُطْلَقِينَ وَ لَا يَؤُمُّ صَاحِبُ الْفَالِجِ الْأَصِحَّاءَ وَ لَا صَاحِبُ التَّيَمُّمِ الْمُتَوَضِّينَ وَ لَا يَؤُمُّ الْأَعْمَى فِي الصَّحْرَاءِ إِلَّا أَنْ يُوَجَّهَ إِلَى الْقِبْلَةِ.
“Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin said, ‘One bonded cannot lead in Salah (prayer) those who are free, one paralyzed cannot lead those in good health, one with Tayammum cannot lead those with Wudu’, a blind cannot lead others in the wilderness unless directed to al-Qiblah (al-Ka‘bah).’”
