٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي الْحَسَنِ (عَلَيْهِ السَّلاَم) قَالَ إِذَا اشْتَرَيْتَ أُضْحِيَّتَكَ وَوَزَنْتَ ثَمَنَهَا وَصَارَتْ فِي رَحْلِكَ فَقَدْ بَلَغَ الْهَدْيُ مَحِلَّهُ فَإِنْ أَحْبَبْتَ أَنْ تَحْلِقَ فَاحْلِقْ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Ali ibn abu Hamzah who has said the following: “Abu al-Hassan ‘Alayhi al-Salam, has said, ‘When you buy your offering animal, measure its price and it becomes as part of your luggage, the offering now has reached its destination, and if you like you can shave your head.’”
