عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ بْنِ مِهْرَانَ قَالَ سَأَلْتُهُ عَنِ الذَّكَاةِ فَقَالَ لَا يُذَكَّى إِلَّا بِحَدِيدَةٍ نَهَى عَنْ ذَلِكَ أَمِيرُ الْمُؤْمِنِينَ ( عليه السلام ) .
4. A number of our people have narrated from Ahmad ibn Muhammad from ibn Khalid from ‘Uthman ibn ‘Isa from Sama‘ah ibn Mehran who has said the following: “I once asked him (the Imam) , about slaughtering. He (the Imam) said, ‘Slaughtering cannot properly be done without iron and ’Amir al-Mu’minin , prohibited slaughtering without it.’”
