Salaamun Alayka,
Sir Joseph,
I'm extremely curious to know since 4 Sunni school of thought (Jurisprudence) precedes Ahadith Corpus, I would like to know if you have in your long research period looked/studied them and their basis? If yes:
- Were they based on the Quran?
- Has any Imam's original work survived and reached us?
Thanks,
~ Student
