Contrary to expections, negation of madhab and hadiths leads to greater fitna as you'll have to repeat history by reinterpreting the Quran and re-formulating principles and over which a 1000 sects will emerge all claiming to follow the right Quran while someone will even go on to claim that certain Quranic verses are daeef. Sunni's instead tap onto the rich history of realiable scholarship connecting us to the Prophet saas.
