٤- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ جَعْفَرِ بْنِ يَحْيَى الْخُزَاعِيِّ عَنْ أَبِيهِ يَحْيَى بْنِ أَبِي الْعَلاءِ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ دَخَلْتُ عَلَى أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) فَخَبَّرْتُهُ أَنَّهُ وُلِدَ لِي غُلامٌ فَقَالَ أَلا سَمَّيْتَهُ مُحَمَّداً قَالَ قُلْتُ قَدْ فَعَلْتُ قَالَ فَلا تَضْرِبْ مُحَمَّداً وَلا تَسُبَّهُ جَعَلَهُ اللهُ قُرَّةَ عَيْنٍ لَكَ فِي حَيَاتِكَ وَخَلَفَ صِدْقٍ مِنْ بَعْدِكَ فَقُلْتُ جُعِلْتُ فِدَاكَ فِي أَيِّ الأعْمَالِ أَضَعُهُ قَالَ إِذَا عَدَلْتَهُ عَنْ خَمْسَةِ أَشْيَاءَ فَضَعْهُ حَيْثُ شِئْتَ لا تُسْلِمْهُ صَيْرَفِيّاً فَإِنَّ الصَّيْرَفِيَّ لا يَسْلَمُ مِنَ الرِّبَا وَلا تُسْلِمْهُ بَيَّاعَ الأكْفَانِ فَإِنَّ صَاحِبَ الأكْفَانِ يَسُرُّهُ الْوَبَاءُ إِذَا كَانَ وَلا تُسْلِمْهُ بَيَّاعَ الطَّعَامِ فَإِنَّهُ لا يَسْلَمُ مِنَ الاحْتِكَارِ وَلا تُسْلِمْهُ جَزَّاراً فَإِنَّ الْجَزَّارَ تُسْلَبُ مِنْهُ الرَّحْمَةُ وَلا تُسْلِمْهُ نَخَّاساً فَإِنَّ رَسُولَ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) قَالَ شَرُّ النَّاسِ مَنْ بَاعَ النَّاسَ.
4. Muhammad ibn Yahya has narrated from Muhammad ibn Ja’far ibn Yahya al-Khuza’iy from his father, Yahya ibn abu al-‘Ala’ from Ishaq ibn ‘Ammar who has said the following: “I once visited abu ‘Abd Allah , and informed him of the birth of my son. He asked, ‘Why do you not name him Muhammad?’ I replied, ‘I have already done so.’ He (the Imam) then said, ‘You must not beat up a Muhammad and do not abuse him. Allah will make him the delight to your eyes during your life time as well as a truthful successor for you.’ I then asked, ‘I pray to Allah to keep my soul in service for your cause, in what kind of profession should I involve him?’ He (the Imam) said, ‘If you keep him away from five kinds of professions then instruct him in whatever you like. You must not train him in money changing business; he will not remain safe from unlawful interest. You must not teach him selling coffins; such people become happy with the coming of plague when such disease is around. You must not teach him in selling foods; they do not remain safe from stockpiling (hoarding) food. Do not instruct him as a butcher; it reduces his kindness. You must not instruct him in how to sell slaves; the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, “The worst people are people sellers.’””
