Every one have the right to belive and disbelive.How ever some arabs who initially joined Islam later apostated.here Apostation doesnt mean NOT observing religious duties rather it is a political revolt. How will a army deal with its members who voluntarily join it, then work with the enemy..? This concept of Murdad doesnt apply to current circumstances not because the law itself is invalid,because the people here just happen to born into some muslim family which is not a voluntary admission. So they are free to choose the religion they want
