That's where one must follow the option where there is caution. If shaikh XYZ says stunning chickens at 1000MV is ok since it's "only sunnah" and shaikh ABC says "then follow the sunnah or stop eating the chickens" are you still going to follow shaikh XYZ? Certainly not! We have a pair of brains, and often the truth is quite clear, just that the nafs refuses to comply...
