حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا جَرِيرٌ عَنْ رَقَبَةَ أَنَّ أَبَا جَعْفَرٍ الْهَاشِمِيَّ الْمَدَنِيَّ كَانَ يَضَعُ أَحَادِيثَ كَلَامَ حَقٍّ وَلَيْسَتْ مِنْ أَحَادِيثِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَكَانَ يَرْوِيهَا عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.

It was narrated from Raqabah that Abu Ja'far Al-Hashimi Al-Madani used to fabricate Hadith, though the words were true, but they were not Ahadith from the Prophet (s.a.w), but he used to report that they were from the Prophet (s.a.w).
