You make me laugh. Sahih Al-Bukhari and Sahih Muslim are considered the most authentic Hadiths. Muhammad Al-Bakhari didn’t just sit down and start writing shit that came to his head. Authentication is a very meticulous process carried out by scholars who work exclusively in the study of Ahadeeth. So don’t pick and choose what you feel is authentic because it doesn’t sound nice. Dismissing that could get you killed in some Muslim lands for disbelief/apostasy, if you didn’t know.

Not satisfied? Surah An-Nuuk 16:126: “If ye punish, then punish with the like of that wherewith ye were afflicted. But if ye endure patiently, verily it is better for the patient.” Another loophole. That’s why ISIS felt it necessary to burn that Jordanian pilot who dropped bombs that burned people. He was Muslim, sure. But an apostate by Islamic standards, so an eye for eye.

Abu-Bakr and Ali burned people. Deal with it.
