The Sufficient (Vol 1) · Hadith 42 (#Ḥadīth #6)

6ـ 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 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 Abi Hamza that he heard Abu ‘Abdillah (al-Sadiq) say, "Acquire good understanding in religion because those of you who do not have good understanding 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)’”
