Congregational Prayer and Its Virtue
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَ رَوَى مُحَمَّدُ بْنُ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «خَمْسَةٌ لاَ يَؤُمُّونَ اَلنَّاسَ وَ لاَ يُصَلُّونَ بِهِمْ صَلاَةً فَرِيضَةً فِي جَمَاعَةٍ اَلْأَبْرَصُ وَ اَلْمَجْذُومُ وَ وَلَدُ اَلزِّنَا وَ اَلْأَعْرَابِيُّ حَتَّى يُهَاجِرَ وَ اَلْمَحْدُودُ.
Muhammad ibn Muslim narrated from Imam Muhammad ibn Ali Al-Baqir عليه السلام who said: "Five people should not lead others in prayer nor should they lead them in a congregational obligatory prayer: the person with leprosy (abrāṣ), the person with a skin disease (majdhūm), the child of adultery (walad al-zina), the Bedouin (a‘rābī) until he migrates, and the person who has been subjected to the legal punishment (al-maḥdūd)."
