2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ إِذَا تَقَيَّأَ الصَّائِمُ فَقَدْ أَفْطَرَ وَإِنْ ذَرَعَهُ مِنْ غَيْرِ أَنْ يَتَقَيَّأَ فَلْيُتِمَّ صَوْمَهُ.
