Freedom of religion from Islamic perspective (2)

I explained previously that Islam guarantees freedom of religion. However, it's well known that if a Muslim converts to another religion then (s)he should be killed! How can that be justified? Well, we need to differentiate between the religion of Islam and a political Islamic regime.

Islam as a religion undoubtedly guarantees freedom of religion and that right is affirmed explicitly in Quraan itself. Nonetheless, the person will be punished in the hereafter.

"And whoso becometh a renegade and dieth in his disbelief: such are they whose works have fallen both in the world and the Hereafter. Such are rightful owners of the Fire: they will abide therein." Quraan 2:217

وَمَن يَرْتَدِدْ مِنكُمْ عَن دِينِهِ فَيَمُتْ وَهُوَ كَافِرٌ فَأُولَئِكَ حَبِطَتْ أَعْمَالُهُمْ فِي الدُّنْيَا وَالآخِرَةِ وَأُولَئِكَ أَصْحَابُ النَّارِ هُمْ فِيهَا خَالِدُونَ
البقرة : ٢١٧

I investigated the issue in history and found no reliable sources indicate that somebody was executed or arrested or tortured because of conversion to another religion during the Prophet's life even though history mentions several occasions for a handful of people converted to different religions during the Prophet's life! I need to investigate this further though, I'll keep a weather eye on this and I will try to provide some known stories and analyze them in coming posts.

However, the case is different with an Islamic regime which is basically a regular political regime that enacts the Islamic laws (Shariah), this enactment is imposed on the people in case of the dictatorial Islamic regime and is voted for by the people in case of the democratic Islamic regime. Nonetheless, an Islamic regime doesn't represent Islam.

If a Muslim converts to another religion, proclaims the conversion and become antagonistic to Islam or the Islamic regime then as any regular political regime a Fatwa/verdict might be issued by a judge (not any person) against this person to either be killed or be punished in a certain way based on the threat (s)he represents. In other words, it's considered as a 'treason' that even at the present time many countries if not most of them still carry out the capital punishment against the traitor.
