Salam.
After reading this report from the UK Times website, and after hearing many murmors from the muslim community, I did some research and consulted my respected teacher, Mufti Jamal Uddin of the New York state in America's Shariah Board. This situation that is being talked about all around the world is making almost all the worlds non-believers question if this Afghani man should be killed 'just' because he left the Faith of Islam. Many say that this is just another barbarity of Islam (I wonder what Dr. Wafa Sultan is saying?) Many muslims also come to ask if this is Justifiable.
Well, of course it complete justice, only because of the Shariah (Law) of Islam is the order of ALLAH, the Almighty and Great. But lets first imagine ourselves in the following situation. If a non-muslim comes to ask you what you think about this man going to get killed, what would you say? You must say something, and you can't just say its the Order of Allah, cause even though its a perfectly good answer, a non-muslim won't take it for an answer. A non-muslim won't because he/she doesn't have the Nur (light) of Islam. So what can one say that'll be understandable to anybody? Personally, when one is troubled with such thoughts, basic human knowledge and logic can always help answer. Abdur Rahman became a Christian from Islam, Islam condems his choice and orders his death. What would a non-muslim say about this. Of course you can almost hear the ignorant criticism of the non-muslims, especially the American Media. Look at whats going on: Afghan children, even those in their first steps, die each day along with many afghans from mines, mines from a war decades ago, and their really isn't any help or aid to save these many people. However when one man needs help law (for logically presumable reasons), he gets a call from the US for his protection. I'm only critisizing the US here. This is the first injustification here.
Secondly, back on the trial of this Murthad (deserter). The laws and understanding of these laws are quite complicated. A murthad, if male, should be put to death but if there is a chance that he might come back to Islam, then, depending on the Situation, the Ulama or ones in charge can devise an intervention that'll give him a choice or rejoining Islam. For example, one might leave Islam because he was threatened if he didn't. Then in the situtation of Women and Children, they are not put to death, but jailed until the reaccept Islam.
Now that we understand the basic rules, we can ask if it is Justifiable on Islamic Terms, which it is. So we are under Haqq (truth/justice) to kill this man because he deserted Islam. The keyword here is 'deserter'. The main reason why Muslims and Non-Muslims alike think this might still be wrong is because in this Day & Age, nationalism (a haram, if valued more than faith) is of more value to the world, rather than Faith. Think about it. For example, in war, when an American Soldier becomes a traitor, he is killed. This is like a unanimously agreed rule among all governments of the world. However, in Islam, if one leaves his Faith, this person is looked at in the same, but worse because he is a traitor of ALLAH, the Almighty and Most Powerful. This traitor is of course going to be killed. Now one might say that I'm speaking pishposh and that Faith and Nationalism isn't the same. The thing is is that they're both valued in the same way, so they are justified the same way.
Lets look at what Isa (Jesus), peace and blessings be upon him, had gone through for example. When he declared the Haqq of Islam, he was chased after the Jews, whom he had betrayed because he saw the Baatil (falsehood) in them. This is pretty understandable. Islam is the Nur and Haqq.
If anyone wants to ask any questions on this topic, please do.
