حَدَّثَنَا مُحَمَّدُ بْنُ الْحَسَنِ رَضِيَ اللَّهُ عَنْهُ قَالَ حَدَّثَنَا سَعْدُ بْنُ عَبْدِ اللَّهِ وَ عَبْدُ اللَّهِ بْنُ جَعْفَرٍ جَمِيعاً عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ حَمْزَةَ بْنِ حُمْرَانَ عَنْ أَبِي عَبْدِ اللَّهِ عليه السلام قَالَ: لَوْ لَمْ يَكُنْ فِي الْأَرْضِ إِلَّا اثْنَانِ لَكَانَ أَحَدُهُمَا الْحُجَّةَ وَ لَوْ ذَهَبَ أَحَدُهُمَا بَقِيَ الْحُجَّةُ.
