Ahmad bin Hanbal (Died 241 AH) narrated :
حدثنا وكيع، حدثنا شعبة، عن الحر بن الصياح، عن عبد الرحمن بن الأخنس، قال: خطبنا المغيرة بن شعبة فنال من علي رضي اللهُ عنه....
Abdur Rahman bin Al-Akhnas said :
Mugheera bin Sho'uba gave us sermon and he abused Ali Ibn Abi Talib.....
Abu Ya'la Mosuli (Died 307 AH) also narrated same narration with same wording.
Ibn Hibban (Died 739 AH) narrated same narratiom with same wording.
Now the same narration is mentioned by Al-Bazzar (Died 292 AH) and he erase out whole first part in which Al-Mugheera was abusing Ali.
