4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي نَجْرَانَ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنِ الْبُدْنِ كَيْفَ تُشْعَرُ قَالَ تُشْعَرُ وَهِيَ مَعْقُولَةٌ وَتُنْحَرُ وَهِيَ قَائِمَةٌ تُشْعَرُ مِنْ جَانِبِهَا الأَيْمَنِ وَيُحْرِمُ صَاحِبُهَا إِذَا قُلِّدَتْ وَأُشْعِرَتْ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn abu Najran from ‘Abd Allah ibn Sinan who has said the following: “I once asked abu ‘Abd Allah , about al-Budn, how it is marked. He (the Imam) said, ‘Mark it when tied down and slaughter it when it is standing. Mark it on its right side and its owner assumes the state of Ihram when something is placed around its neck or is marked.’”
