10ـ أَحْمَدُ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْعَرْزَمِيِّ عَنْ أَبِي عَبْدِ الله عَنْ أَبِيهِ عَنْ عَلِيٍّ (عَلَيْهِ السَّلاَم) قَالَ يَقْتُلُ الْمُحْرِمُ كُلَّ مَا خَشِيَهُ عَلَى نَفْسِهِ.
10. Ahmad has narrated from Ali ibn al-Hakam from ‘Abd al-Rahman al-‘Arzamiy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘One in the state of Ihram can kill anything whereby one fears for his life.’”
