عَلِيٌّ عَنْ اَخِيهِ مُوسَى ع قَالَ: كَانَ يَقُولُ قَبْلَ اَنْ يُؤْخَذَ بِسَنَةٍ اِذَا اجْتَمَعَ عِنْدَهُ اَهْلُ بَيْتِهِ مَا وَكَّدَ اللهُ عَلَى الْعِبَادِ فِي شَيْءٍ مَا وَكَّدَ عَلَيْهِمْ بِالْاِقْرَارِ بِالْاِمَامَةِ وَ مَا جَحَدَ الْعِبَادُ شَيْئًا مَا جَحَدُوهَا.
Ali Ibn Ja’far al-Sadeq (peace be upon him) reports from his brother (Imam) Moosa (al-Kazim) (peace be upon him) who used to say a year before his death when his family members gathered around him (peace be upon him),
“Allah has not emphasized on anything so much for the servants as much as He has emphasized on acknowledgement of Imamate but the people have not denied anything as much as they have denied Imamate.”
