The One Praying Who Needs to Relieve Himself
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 54
وَ رَوَى مُحَمَّدُ بْنُ بَجِيلٍ أَخُو عَلِيِّ بْنِ بَجِيلٍ قَالَ: رَأَيْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ يُصَلِّي فَمَرَّ بِهِ رَجُلٌ وَ هُوَ بَيْنَ اَلسَّجْدَتَيْنِ فَرَمَاهُ أَبُو عَبْدِ اَللَّهِ بِحَصَاةٍ فَأَقْبَلَ اَلرَّجُلُ إِلَيْهِ.
Muhammad ibn Bajil, the brother of Ali ibn Bajil, narrated: "I saw Imam Jafar ibn Muhammad Al-Sadiq عليه السلام praying, and a man passed by him while he was between the two prostrations. Abu Abdullah عليه السلام threw a small stone at him, and the man came towards him."
