احسن الله إليك Shaykh bin Uthaymin mentioned that all of the sahabah were 'udul in the explanation of mubham. I ask, where they all also daabit (precise)? ‏جزاك الله خيرا

The question should be is their saying evidence rather than asking this may Allah rewaed you, and yes it is if no other sahabi contradicts it and it is widespread and known.
