9ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ بْنِ بَزِيعٍ عَنْ عَمِّهِ حَمْزَةَ بْنِ بَزِيعٍ عَنْ عَلِيِّ بْنِ سُوَيْدٍ عَنْ أَبِي الْحَسَنِ مُوسَى بْنِ جَعْفَرٍ (عَلَيْهما السَّلام) فِي قَوْلِ الله عَزَّ وَجَلَّ يا حَسْرَتى‏ عَلى‏ ما فَرَّطْتُ فِي جَنْبِ الله قَالَ جَنْبُ الله أَمِيرُ الْمُؤْمِنِينَ (عَلَيْهِ السَّلام) وَكَذَلِكَ مَا كَانَ بَعْدَهُ مِنَ الاوْصِيَاءِ بِالْمَكَانِ الرَّفِيعِ إِلَى أَنْ يَنْتَهِيَ الامْرُ إِلَى آخِرِهِمْ.

9. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Muhammad ibn Isma‘il ibn Bazi‘a from his uncle Hamza ibn Bazi‘a from Ali ibn Suwayd from abu al-Hassan Musa ibn Ja‘far (a.s.) who has said the following. About the words of Allah “Woe to me because of my failure to fulfill my duties from the side of God. .” (39:56). The Imam (a.s.) said that the side of Allah is Amirul Mu’minin (a.s.) and so are the successors of the high position until the matters will reach to the last one among them.”
