 ١ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ وَعَبْدِ الله ابْنَيْ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ سَيْفِ بْنِ عَمِيرَةَ عَنْ مُفَضَّلِ بْنِ يَزِيدَ قَالَ قَالَ لِي أَبُو عَبْدِ الله (عَلَيْهِ السَّلام) أَنْهَاكَ عَنْ خَصْلَتَيْنِ فِيهِمَا هَلاكُ الرِّجَالِ أَنْهَاكَ أَنْ تَدِينَ الله بِالْبَاطِلِ وَتُفْتِيَ النَّاسَ بِمَا لا تَعْلَمُ.
 1. Muhammad ibn Yahya has narrated from Ahmad and ‘Abdallah (both) sons of Muhammad ibn ‘Isa from Ali ibn al-Hakam from Sayf ibn ‘Umayra from Mufaddal ibn Yazid who has said the following. “(Imam) abu ‘Abdallah said, ‘I would like to warn you about two forms of behavior that lead a man to destruction. I prohibit you from dealing with Allah on the basis of falsehood and from giving fatwa to people without knowledge.’”
