مَا حَدَّثَنِی بِهِ مُحَمَّدُ بْنُ الْحَسَنِ قَالَ حَدَّثَنَا الْحُسَیْنُ بْنُ الْحَسَنِ بْنِ أَبَانٍ عَنِ الْحُسَیْنِ بْنِ سَعِیدٍ عَنِ ابْنِ أَبِی عُمَیْرٍ عَنِ ابْنِ أُذَیْنَهَ عَنْ زُرَارَهَ عَنْ أَبِی جَعْفَرٍ ع قَالَ: مَنْ لَمْ یُصَلِّ مَعَ الْإِمَامِ فِی جَمَاعَهٍ یَوْمَ الْعِیدِ فَلَا صَلَاهَ لَهُ وَ لَا قَضَاءَ عَلَیْهِ.
