 ٦ـ عَلِيُّ بْنُ مُحَمَّدِ بْنِ عَبْدِ الله عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلام) يَقُولُ تَفَقَّهُوا فِي الدِّينِ فَإِنَّهُ مَنْ لَمْ يَتَفَقَّهْ مِنْكُمْ فِي الدِّينِ فَهُوَ أَعْرَابِيٌّ إِنَّ الله يَقُولُ فِي كِتَابِهِ لِيَتَفَقَّهُوا فِي الدِّينِ وَلِيُنْذِرُوا قَوْمَهُمْ إِذا رَجَعُوا إِلَيْهِمْ لَعَلَّهُمْ يَحْذَرُونَ.
 6. Ali ibn Muhammad ibn ‘Abdallah has narrated from Ahmad ibn Muhammad ibn Khalid from ‘Uthman ibn ‘Isa from Ali ibn abu Hamza who has said the following. “I heard Imam abu ‘Abdallah saying, ‘Acquire good understand in religion because those of you who do not have good understand in religion are like the Bedouins. Allah has said in His book, ‘ Why do not some people from each group of believers seek to become specialists in religious learning and, after completing their studies, guide their group so that they will have fear of God. (9:122)’”
