مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ مُوسَى بْنِ بَكْرٍ قَالَ قَالَ لِي أَبُو الْحَسَنِ يَعْنِي الْأَوَّلَ ( عليه السلام ) مَا لِي أَرَاكَ مُصْفَرّاً فَقُلْتُ لَهُ وَعَكٌ أَصَابَنِي فَقَالَ لِي كُلِ اللَّحْمَ فَأَكَلْتُهُ ثُمَّ رَآنِي بَعْدَ جُمْعَةٍ وَ أَنَا عَلَى حَالِي مُصْفَرّاً فَقَالَ لِي أَ لَمْ آمُرْكَ بِأَكْلِ اللَّحْمِ قُلْتُ مَا أَكَلْتُ غَيْرَهُ مُنْذُ أَمَرْتَنِي فَقَالَ وَ كَيْفَ تَأْكُلُهُ قُلْتُ طَبِيخاً فَقَالَ لَا كُلْهُ كَبَاباً فَأَكَلْتُهُ ثُمَّ أَرْسَلَ إِلَيَّ فَدَعَانِي بَعْدَ جُمْعَةٍ وَ إِذَا الدَّمُ قَدْ عَادَ فِي وَجْهِي فَقَالَ لِي الْآنَ نَعَمْ .
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn Sinan from Musa ibn Bakr who has said the following: “Once abu al-Hassan, al- Awwal asked me, ‘Why do you look pale?’ I replied, ‘I suffer from a certain pain.’ He (the Imam) said, ‘Eat meat.’ I ate meat and the next Friday he (the Imam) saw me as pale as before and said, ‘Did I not tell you to eat meat?’ I replied, ‘Yes, I have not eaten anything other than meat from the day you instructed me.’ He (the Imam) then asked, ‘How did you eat?’ I replied, ‘I ate as mixed with other items.’ He (the Imam) said, ‘No, eat as kabab.’ I then ate kabab and he (the Imam) sent for me next Friday when my blood level had come back in my face, and he (the Imam) said to me, ‘Now it is good, you are fine.’”
