وَعَنْهُ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ سَمِعْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ يَقُولُ:« اَلْقَامَةُ هِيَ اَلذِّرَاعُ»
And from him, from Ali ibn Asbat, from Ali ibn Abi Hamzah, who said:
I heard Abu Abdillah عليه السلام say: “The ‘qamah’ is the ‘dhira’.”
