Chapter on Mutual Cursing (Li'an)
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 19
وَ سَأَلَ اَلْبَزَنْطِيُّ أَبَا اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: فَقَالَ لَهُ أَصْلَحَكَ اَللَّهُ كَيْفَ اَلْمُلاَعَنَةُ قَالَ "يَقْعُدُ اَلْإِمَامُ وَ يَجْعَلُ ظَهْرَهُ إِلَى اَلْقِبْلَةِ وَ يَجْعَلُ اَلرَّجُلَ عَنْ يَمِينِهِ وَ اَلْمَرْأَةَ وَ اَلصَّبِيَّ عَنْ يَسَارِهِ".
Al-Bazanti asked Abu Al-Hasan Imam Ali ibn Musa Ar-Ridha عليه السلام: "May Allah سبحانه وتعالى rectify your affairs, how is the procedure of liʿan (mutual cursing) carried out?" Imam عليه السلام replied: "The Imam sits with his back facing the Qibla, placing the man on his right side and the woman along with the child on his left side."
