Islam ,,,,, way to a successfull life.
Islam is the only religion, that apply its laws universally. There is no difference of religion while punishing a criminal. For example: a murderer is a criminal and should be punished, no matter he/she is a Muslim or non_Muslim. According to Islamic law, when a Muslim converts to another religion, he/she must be killed. Following are the main reason for this order, according to my little knowledge.
1: A practicing Muslim is bound to the orders of Allah Almighty. His/Her every action is for the sake of Allah And for the betterment of His people. He/She takes every single step for the betterment of the people of Allah Almighty and thinks for a hundred times while taking any decision that it should not harm the other people. So he is very bound in Islam.
2: Islam doesn’t allow any Muslim to look even to the face of a stranger man or woman. Its a sin for a Muslim.
3: A Muslim is not allowed to tell a lie. Muslim is not allowed to show raged. Rage is Haram for a Muslim.
4: He/she must take care of poor people,his/her neighbour, his/her relatives and even unknown people and he/she must help them in need.
5: He/she must have to pay zakat(specific amount of money applicable on rich Muslims) for the welfare of poor and needy people and rich people are bound to pay it.
6: He/she must obey and serves his/her parents and if they disobey their parents they will become sinner.
7: Muslims live a very bounded life.And if he/she practices Islam,he/she is a very use full and help full member of the human society and proves better for everyone.
8: He/she is not allowed to do any evil deed.When he/she disobey the rules of religion they must be punished strictly.
9: In Islam if they do theft, their one hand should be cut off.If they do a murder they must be killed in punishment, so they don’t try to do such evil deeds.
These are the Reasons that a non practicing internally a fake Muslim feels bound in Islam. Such a bounded person, when sett free, can be harm full to the human community.Because In other religion for example in Christianity,they can be released from their sins after doing a single Confession against a priest.no matter how much blunders they did. So from such bounded environment of Islam when they came to such an environment with unlimited freedom, they can prove very dangerous for the other members of society.
So that’s why,if a Muslim converts to another religion he/she must be killed to save the other human being from his her evil deeds and harms.
