إِذَا امْتَنَعَ عَلَيْكَ بَعِيرٌ وَ أَنْتَ تُرِيدُ أَنْ تَنْحَرَهُ فَانْطَلَقَ مِنْكَ فَإِنْ خَشِيتَ أَنْ يَسْبِقَكَ فَضَرَبْتَهُ بِسَيْفٍ أَوْ طَعَنْتَهُ بِرُمْحٍ بَعْدَ أَنْ تُسَمِّيَ فَكُلْ إِلَّا أَنْ تُدْرِكَهُ وَ لَمْ يَمُتْ بَعْدُ فَذَكِّهِ.
“Abu ‘Abd Allah (a.s.), has said that once in al-Kufah a bull revolted and broke loose. People rushed with their swords and beat it down. They asked ’Amir al-Mu’minin (a.s.), about it and he (the Imam) said, ‘It is a fast slaughtering but its flesh is lawful for food.’”
