Hadith 57:80
Abd Allah bin Abd ar-Rahman ad-Dārimī narrated to us, Zakariyyā’ bin Adī informed us, he said, Abū Ishāq al-Fazarī said to me:
‘Write from Baqiyyah what he transmits on authority of those who are well-known, and do not write from him what he transmits on authority of those who are not; do not write from Ismā’īl bin Ayyāsh what he transmits on authority of those who are well-known or otherwise ’.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ الدَّارِمِيُّ، أَخْبَرَنَا زَكَرِيَّاءُ بْنُ عَدِيٍّ، قَالَ قَالَ لِي أَبُو إِسْحَاقَ الْفَزَارِيُّ اكْتُبْ عَنْ بَقِيَّةَ، مَا رَوَى عَنِ الْمَعْرُوفِينَ، وَلاَ تَكْتُبْ عَنْهُ مَا رَوَى عَنْ غَيْرِ الْمَعْرُوفِينَ، وَلاَ تَكْتُبْ عَنْ إِسْمَاعِيلَ بْنِ عَيَّاشٍ، مَا رَوَى عَنِ الْمَعْرُوفِينَ، وَلاَ عَنْ غَيْرِهِمْ،
