Why Haven’T Sunnis Transmitted Hadiths From Ahlul Bayt
Imam Jafar’s fiqh was not compiled as reliably as that of Imam Abu Laith, Imam Sufyan Thauri, and mothers. Most the narrators of imam Jafar were Iraqis and they are not considered trustworthy.
As I told you that there were other great scholars but their fiqh was not recorded too. Not every scholar could gather competent disciples to record their work. The principles of Fiqh Hanafi are known, open to review. If there is anything suspicious one can point it out.
