I've recently come accross few narrations regarding apostacy and I started experience a bad feeling, worrying if my religion (God forbid) was somehow unjust. We have plenty saying that the one who belies his shahada should be killed.
My question is as follow : Why is it so ? In general are the apostates who genuinely leave Islam (in a islamic state with a maasoum or a just faqih) without betraying the community to be killed ?
