Hadith #4

عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ ( عليه السلام ) أَنَّهُ كَرِهَ صَيْدَ الْبَازِي إِلَّا مَا أُدْرِكَتْ ذَكَاتُهُ .

4. Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa from Hariz from Muhammad ibn Muslim who has said the following: “Abu Ja‘far, ‘Alayhi al-Salam, disliked what a falcon hunted unless one arrived in time to slaughter it properly.’”
