 ١ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ زُرَارَةَ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ السَّلام) اعْرِفْ إِمَامَكَ فَإِنَّكَ إِذَا عَرَفْتَ لَمْ يَضُرَّكَ تَقَدَّمَ هَذَا الامْرُ أَوْ تَأَخَّرَ.
 1. Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa from Hariz from Zurara who has said the following. “Abu ‘Abdallah  has said, ‘Learn who your Imam is. When you learn who he is then it will have no affect on you whether this matter (the rise of al-Mahdi with Divine Authority) will take place earlier or later.”
