Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «لاَ يَؤُمُّ صَاحِبُ اَلْقَيْدِ اَلْمُطْلَقِينَ وَ لاَ يَؤُمُّ صَاحِبُ اَلْفَالِجِ اَلْأَصِحَّاءَ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "A person in chains (al-qayd) does not lead those who are free, and a person afflicted with paralysis (al-falij) does not lead those who are healthy."
