Death of Thaba Baba
While I personally believe Thaba Baba was a (something I don't wanna say), killing him was not the Islamic Way. The Jamat-Shibir (slang)s are using the name of our religion for their own personal gain. When someone opposes our Prophet Muhammad Sallallahu Alaihi Was Sallam, we talk through to them. That's how it was always done in the time of our Prophet Sallallahu Alaihi Was Sallam and afterwards. Look at Zakir Naik for examples. That is how you preach Islam, not by putting a knife to someones throat and say "Convert or else".
Their punishment is due. The Jamat-Shibir (slang)s will burn in hell in the Afterlife for the rest of the Afterlife.
