3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ الْبَرْقِيِّ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله يَقُولُ مَنْ عَلَّمَ خَيْراً فَلَهُ مِثْلُ أَجْرِ مَنْ عَمِلَ بِهِ قُلْتُ فَإِنْ عَلَّمَهُ غَيْرَهُ يَجْرِي ذَلِكَ لَهُ قَالَ إِنْ عَلَّمَهُ النَّاسَ كُلَّهُمْ جَرَى لَهُ قُلْتُ فَإِنْ مَاتَ قَالَ وَإِنْ مَاتَ.
3. Ali ibn Ibrahim has narrated from Ahmad ibn Muhammad al-Barqi from Ali ibn al-Hakam from Ali ibn abu Hamza from abu Basir from abu ‘Abdallah who has said the following. “Whoever teaches something good he will receive a reward for each time his student would practice such knowledge.” Abu Basir has said, “I asked the Imam, ‘Would this apply to the student if he would teach other people?’ The Imam replied, “Yes, it will apply to him even if all people would teach it.” I then asked, ‘Would it apply to him if he would already be dead?’ The Imam responded, “Yes, even if he would be dead.”’
