4- حَدَّثَنَا أَبِي رَضِيَ اللَّهُ عَنْهُ قَالَ حَدَّثَنَا سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ الْعَلَوِيِّ عَنْ أَبِي هَاشِمٍ الْجَعْفَرِيِّ قَالَ سَمِعْتُ أَبَا الْحَسَنِ الْعَسْكَرِيَّ ع يَقُولُ الْخَلَفُ مِنْ بَعْدِي الْحَسَنُ ابْنِي فَكَيْفَ لَكُمْ بِالْخَلَفِ مِنْ بَعْدِ الْخَلَفِ قُلْتُ وَ لِمَ جَعَلَنِيَ اللَّهُ فِدَاكَ قَالَ لِأَنَّكُمْ لَا تَرَوْنَ شَخْصَهُ وَ لَا يَحِلُّ لَكُمْ ذِكْرُهُ بِاسْمِهِ قُلْتُ فَكَيْفَ نَذْكُرُهُ فَقَالَ قُولُوا الْحُجَّةُ مِنْ آلِ مُحَمَّدٍ ص.
4 - Narrated to us my father: Narrated to us Saad bin Abdullah from Muhammad bin Ahmad Alawi from Abi Hashim Ja’fari that he said: I heard Abul Hasan Askari 
[Imam Hadi] say:
“The Imam after me is my son, Hasan. How will you behave with his son? I said: May I be sacrificed on you, why did you ask that? He replied: Neither will you be able to see him nor uttering his name will be allowed for you. I asked: Then how do we mention him? He replied: The Proof from Aale Muhammad (S).”
