 ٤ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ أَبِي الرَّبِيعِ الْقَزَّازِ عَنْ جَابِرٍ عَنْ ابي جعفر (عَلَيْهِ السَّلام) قَالَ قُلْتُ لَهُ لِمَ سُمِّيَ أَمِيرَ الْمُؤْمِنِينَ قَالَ الله سَمَّاهُ وَهَكَذَا أَنْزَلَ فِي كِتَابِهِ وَإِذْ أَخَذَ رَبُّكَ مِنْ بَنِي آدَمَ مِنْ ظُهُورِهِمْ ذُرِّيَّتَهُمْ وَأَشْهَدَهُمْ عَلى‏ أَنْفُسِهِمْ أَ لَسْتُ بِرَبِّكُمْ وَأَنَّ مُحَمَّداً رَسُولِي وَأَنَّ عَلِيّاً أَمِيرُ الْمُؤْمِنِينَ.

Ali ibn Ibrahim has narrated from ya‘qub ibn Yazid from Ibn Abi ‘Umayr from abu al-Rabi‘ al-Qazzaz from Jabir who has said the following. “I asked abu Ja‘far , ‘Why is he (Ali ibn abu Talib  is called Amir al-Mu’minin ?” He said, “Allah has given him this name and as such it has come in His book, “When your Lord asked all the offspring of Adam (before their birth), “Am I not your Lord?” All of them testified and bore witness to their testimony that on the Day of Judgment they would not say, “We were not aware of this (fact),.” (7:172) that Muhammad is My messenger and Ali is Amir al-Mu’minin (commander of the faithful).”
