9ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ حَفْصِ بْنِ الْبَخْتَرِيِّ عَنْ أَبِي حَلاَّلٍ الرَّازِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنْ رَجُلَيْنِ اقْتَتَلا وَهُمَا مُحْرِمَانِ قَالَ سُبْحَانَ الله بِئْسَ مَا صَنَعَا قُلْتُ قَدْ فَعَلا فَمَا الَّذِي يَلْزَمُهُمَا قَالَ عَلَى كُلِّ وَاحِدٍ مِنْهُمَا دَمٌ.

9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Hafs ibn al-Bakhtariy from abu Halal al-Raziy who has said the following: “I once asked abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of two men who fought each other while in the state of Ihram. He (the Imam) said, ‘Allah is free of all defects, how bad is what they have done!’ I said, ‘They have done it but what must they do?’ He (the Imam) said, ‘They must each offer one animal as offering.’”
