I always thought that only sahih albukhari and sahih muslim are the only 100% correct sources of hadiths and pretty much ignored other sources until I found this thread: How do we make sure if a Hadith is sahih or fake?
My question is: Is basing the authenticity of a hadith based on its source even right?
Can someone consider the sources above 100% true? and is there any other sources to be considered as true so one can easily learn from from them without having the trouble to check authenticity for a hadith each time, which will create some unwanted doubt in every hadith heard?
