Congregational Prayer and Its Virtue
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَقَالَ اَلْبَاقِرُ وَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «لاَ بَأْسَ أَنْ يَؤُمَّ اَلْأَعْمَى إِذَا رَضُوا بِهِ وَ كَانَ أَكْثَرَهُمْ قِرَاءَةً وَ أَفْقَهَهُمْ.
Imam Muhammad ibn Ali Al-Baqir عليه السلام and Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "There is no issue for a blind person to lead the prayer if the people (praying behind him) are satisfied with him and he is the best among them in recitation and the most knowledgeable in religious jurisprudence."
