و حَدَّثَنَا أَبُو جَعْفَرٍ الدَّارِمِيُّ حَدَّثَنَا بِشْرُ بْنُ عُمَرَ قَالَ سَأَلْتُ مَالِكَ بْنَ أَنَسٍ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ الَّذِي يَرْوِي عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ فَقَالَ لَيْسَ بِثِقَةٍ وَسَأَلْتُهُ عَنْ صَالِحٍ مَوْلَى التَّوْأَمَةِ فَقَالَ لَيْسَ بِثِقَةٍ وَسَأَلْتُهُ عَنْ أَبِي الْحُوَيْرِثِ فَقَالَ لَيْسَ بِثِقَةٍ وَسَأَلْتُهُ عَنْ شُعْبَةَ الَّذِي رَوَى عَنْهُ ابْنُ أَبِي ذِئْبٍ فَقَالَ لَيْسَ بِثِقَةٍ وَسَأَلْتُهُ عَنْ حَرَامِ بْنِ عُثْمَانَ فَقَالَ لَيْسَ بِثِقَةٍ وَسَأَلْتُ مَالِكًا عَنْ هَؤُلَاءِ الْخَمْسَةِ فَقَالَ لَيْسُوا بِثِقَةٍ فِي حَدِيثِهِمْ وَسَأَلْتُهُ عَنْ رَجُلٍ آخَرَ نَسِيتُ اسْمَهُ فَقَالَ هَلْ رَأَيْتَهُ فِي كُتُبِي قُلْتُ لَا قَالَ لَوْ كَانَ ثِقَةً لَرَأَيْتَهُ فِي كُتُبِي.

Bishr bin 'Umar said: "I asked Malik bin Anas about Muhammad bin 'Abdur-Rahman, who narrated from Sa'eed bin Al-Musayyab. He said: 'He is not trustworthy.' I asked Malik bin Anas about Abu Al-Huwairith. He said: 'He is not trustworthy.' I asked him about Shu'bah from whom Ibn Abi Dhi'b narrated. He said: 'He is not trustworthy.' I asked him about Salilh, the freed slave of At-Taw'amah. He said: 'He is not trustworthy.' I asked him about Haram bin 'Uthman. He said: 'He is not trustworthy.' I asked Malik about these five. He said: 'They are not trustworthy in their Ahadith.' I asked him about another man whose name I have forgotten and he said: 'Have you seen him in my books?' I said: 'No.' He said: 'If he were trustworthy, you would have seen him in my books.'"
