I have been raised a sunni and am still a sunni, but after reading some history, I am beginning to have doubts about Sahih Bukhari, Sahih Muslim and other sunni books. Particularly troubling to me is the fact that sunni scholars accepted ahadith from those who fought against Ali bin Abi Talib, Al Hussain bin Ali etc., and even from those who were not Sahaba and fought against Sahaba, such as Abdul Malak bin Marwan. I want to know about all Banu Umayyah and their supporters who are accepted as narrators in especially Bukhari and Muslim, and also in other sunni books. The best thing would be to have a reference to all the ahadith in Bukhari and Muslim and other sunni books which contain in their isnad Muawiya bin Abu Sufyan and his supporters, Yazid bin Muawiya and his supporters and similarly other rulers of Banu Umayya and their supporters. Is there any place where I can find this information? The alternative would be for me to go over all the narrators in all the sunni hadith books to check if they were supporters of Banu Umayyah, and this would take me a lifetime.
