Unity could you please post the passages about death to the apostate and the other option of exile.
Do you however understand the implications of being sent in exile; of leaving your home, property and attempt to settle probably in a alien country from shread; have you considered the dangers, the poverty, the loneliness, the unsafety etc.
In what sense does this second option vindicate the justice of Islam.
The bottom line is in Islam, anyone who personally chooses to leave his faith and become (say) a Christians is condemned to suffer.
Any provide the passages.
