 ٩ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنْ عَبْدِ الله بْنِ مُسْكَانَ عَنْ دَاوُدَ بْنِ فَرْقَدٍ عَنْ أَبِي سَعِيدٍ الزُّهْرِيِّ عَنْ ابي جعفر (عَلَيْهِ السَّلام) قَالَ الْوُقُوفُ عِنْدَ الشُّبْهَةِ خَيْرٌ مِنَ الاقْتِحَامِ فِي الْهَلَكَةِ وَتَرْكُكَ حَدِيثاً لَمْ تُرْوَهُ خَيْرٌ مِنْ رِوَايَتِكَ حَدِيثاً لَمْ تُحْصِهِ.
 9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn an-Ni‘man from ‘Abdallah ibn Muskan from Daiwud ibn Farqad from abu Sa‘id al-Zuhri from abu Ja’far  who has said the following. “Holding back in an uncertain conditions is better than indulging in a destructive case. Your ignoring a Hadith that you do not narrate is better than your narrating a Hadith that you have not verified.”
