 ٤ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُحَمَّدِ بْنِ حُمْرَانَ عَنْ أَبِي عُبَيْدَةَ الْحَذَّاءِ قَالَ قَالَ أَبُو جَعْفَرٍ (عَلَيْهِ السَّلام) يَا زِيَادُ إِيَّاكَ وَالْخُصُومَاتِ فَإِنَّهَا تُورِثُ الشَّكَّ وَتَهْبِطُ الْعَمَلَ وَتُرْدِي صَاحِبَهَا وَعَسَى أَنْ يَتَكَلَّمَ بِالشَّيْ‏ءِ فَلا يُغْفَرَ لَهُ إِنَّهُ كَانَ فِيمَا مَضَى قَوْمٌ تَرَكُوا عِلْمَ مَا وُكِّلُوا بِهِ وَطَلَبُوا عِلْمَ مَا كُفُوهُ حَتَّى انْتَهَى كَلامُهُمْ إِلَى الله فَتَحَيَّرُوا حَتَّى إِنْ كَانَ الرَّجُلُ لَيُدْعَى مِنْ بَيْنِ يَدَيْهِ فَيُجِيبُ مِنْ خَلْفِهِ وَيُدْعَى مِنْ خَلْفِهِ فَيُجِيبُ مِنْ بَيْنِ يَدَيْهِ وَفِي رِوَايَةٍ أُخْرَى حَتَّى تَاهُوا فِي الارْضِ.
 4. A group of our people has narrated from Ahmad ibn Muhammad ibn Khalid from his father from Ibn Abi ‘Umayr from Muhammad ibn Humran from abu ‘Ubaydah (Ziyad ibn ‘Isa) al-Hadhdha’ from Imam abu Ja‘far  who has said the following. “O Ziyad, beware of debates because they create doubts, invalidate one’s good deeds and turn one into a complete wreck. One may say a thing, perhaps, he will not be forgiven. In the past there lived a people who ignored acquiring the necessary knowledge and instead they sought a knowledge that was not required of them. They came to speak of Allah’s self and they became confused. Their extreme perplexity was such that if called from the front they would reply to the back and to the front if called from the back.’” In another Hadith it reads, “They totally banished on earth.”
