20ـ إِسْحَاقُ قَالَ أَخْبَرَنِي مُحَمَّدُ بْنُ الرَّبِيعِ الشَّائِيُّ قَالَ نَاظَرْتُ رَجُلاً مِنَ الثَّنَوِيَّةِ بِالاهْوَازِ ثُمَّ قَدِمْتُ سُرَّ مَنْ رَأَى وَقَدْ عَلِقَ بِقَلْبِي شَيْءٌ مِنْ مَقَالَتِهِ فَإِنِّي لَجَالِسٌ عَلَى بَابِ أَحْمَدَ بْنِ الْخَضِيبِ إِذْ أَقْبَلَ أَبُو مُحَمَّدٍ (عَلَيْهِ السَّلام) مِنْ دَارِ الْعَامَّةِ يَؤُمُّ الْمَوْكِبَ فَنَظَرَ إِلَيَّ وَأَشَارَ بِسَبَّاحَتِهِ أَحَدٌ أَحَدٌ فَرْدٌ فَسَقَطْتُ مَغْشِيّاً عَلَيَّ.
20. Ishaq has said that narrated to me Muhammad ibn al-Rabi‘ al-Sa’i has said the following.
“I debated a man who believed in dualism in Ahwaz them went to Surra man Ra‘a. However, his words were stuck to my heart. I was sitting in front of the door of Ahmad al-Khadib that I saw abu Muhammad 
coming from the house for public gathering. It was the house wherein on a certain day the Sultan would allow the common people to visit him. The Imam looked at me and made a gesture with his forefinger say One, single and only One. I fainted and fell on my face.”
