You mean such kind of apostate within muslim country?
Well the Quran and Hadith states that the apostate who separates from the Jama'ah(muslims) and joins the enemies, is to be killed. Or the apostate that goes against the law and order, publicly calling for disbelief and insults the religion Or calls to uprising. We are talking about warlike apostasy. At the time of prophet pbuh apostates would ofcourse join the enemies(makkan polytheists). So this is treason.
With warlike apostasy i dont mean apostate that challenges muslims in debates on tv aslong it happens in respectful way.
To give example of warlike apostates by naming people i think most cases about ayaan hersi ali, salman rushdi.
However i never agreed with killing peaceful apostates. Muslims who left the religion, they mind their own business by going to church/synagogue/atheistBowling ( ). It goes against Quran and Sunnah.
This might be because I've grown up in a vastly different culture, but I believe that religion has no business in government. It shouldn't be used to control a country's citizens, or be a part of making and enacting laws. People should be free to worship as they wish, anywhere in the world. There should be no wars 'defending' religions. It's just beyond absurd to me. lol Religion should be a private thing, it should help bring a person closer to God, if that is what they wish to do. Even if atheists talk against a particular religion, who cares? It shouldn't rattle someone whose faith is strong. When spirituality becomes a tool to control people with, it loses its beauty and becomes nothing remotely resembling faith. That's just my opinion.
