مُحَمَّدُ بْنُ يَعْقُوبَ عَنْ عَلِيِّ بْنِ إِبْرَاهِيمَ رَفَعَهُ قَالَ: رَأَيْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ يُصَلِّي بِقَوْمٍ وَ هُوَ إِلَى زَاوِيَةٍ فِي بَيْتٍ بِقُرْبِ اَلْحَائِطِ وَ كُلُّهُمْ عَنْ يَمِينِهِ وَ لَيْسَ عَنْ يَسَارِهِ أَحَدٌ

Muhammad ibn Yaqub from Ali ibn Ibrahim in a ‘marfu’ (elevated) chain said: I saw Aba Abdillah , peace be upon him, leading a group in prayer, and Imam was in a corner of a house near the wall, and all of them were to his right, and there was no one to his left.
