3- حَدَّثَنَا أَبِي رَضِيَ اللَّهُ عَنْهُ قَالَ حَدَّثَنَا سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ إِسْمَاعِيلَ بْنِ مِهْرَانَ عَنْ مُحَمَّدِ بْنِ سَعِيدٍ عَنْ أَبَانِ بْنِ تَغْلِبَ قَالَ: قُلْتُ لِأَبِي عَبْدِ اللَّهِ ع مَنْ عَرَفَ الْأَئِمَّةَ وَ لَمْ يَعْرِفِ الْإِمَامَ الَّذِي فِي زَمَانِهِ أَ مُؤْمِنٌ هُوَ قَالَ لَا قُلْتُ أَ مُسْلِمٌ هُوَ قَالَ نَعَمْ.
3 - Narrated to us my father (r.a.): Narrated to us Saad bin Abdullah from Muhammad bin Isa from Ismail bin Mehran from Muhammad bin Saeed from Aban bin Taghlib that he said: I asked Abi Abdullah 
:
“Is he a believer, that has cognition of the previous Imams but does not have cognition of the Imam of his time? He replied: No. I asked: Is he is a Muslim? He replied: Yes.”
