مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ خَالِدٍ عَنْ سَعْدِ بْنِ سَعْدٍ قَالَ قُلْتُ لِأَبِي الْحَسَنِ ( عليه السلام ) إِنَّ أَهْلَ بَيْتِي لَا يَأْكُلُونَ لَحْمَ الضَّأْنِ قَالَ فَقَالَ وَ لِمَ قَالَ قُلْتُ إِنَّهُمْ يَقُولُونَ إِنَّهُ يُهَيِّجُ بِهِمُ الْمِرَّةَ السَّوْدَاءَ وَ الصُّدَاعَ وَ الْأَوْجَاعَ فَقَالَ لِي يَا سَعْدُ فَقُلْتُ لَبَّيْكَ قَالَ لَوْ عَلِمَ اللَّهُ عَزَّ وَ جَلَّ شَيْئاً أَكْرَمَ مِنَ الضَّأْنِ لَفَدَى بِهِ إِسْمَاعِيلَ ( عليه السلام ) .
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn Khalid from Sa‘d ibn Sa‘d who has said the following: “I once said to abu al-Hassan , ‘My family does not like the meat of sheep.’ He (the Imam) then asked, ‘Why do they not like it?’ I replied, ‘They say that it accelerates bitterness, headache and pains.’ He (the Imam) said, ‘O Sa‘d.’ I replied, ‘Yes, my Imam.’ He (the Imam) said, ‘Had Allah, most Majestic, most Glorious, considered anything more revered than sheep He would have presented it instead (of the ram) as ransom for Ismail .’”
