@Dawo shariah law is perfect, however it allows for the manoveur of qiyaas and ijtihaad and frankly I don't trust any of these dubious people at the moment. The sahabah were different.
Qiyas and ijtihaad is part of islam, we can't come with that logic and label people dubious so the four imams of ahlul sunnah you were dubious of their teachings ?
