Over the last few days I received a number of emails and messages expressing great disillusion with what has happened at Fort Hood. This is your chance to vent, offer your thoughts and share in the healing process. One of the positive, out of many, things I’ve noticed is the idea of taking responsibility as a community and addressing the sources and wells for which unhealthy thoughts and illegal ideas come from. This is your chance to share and offer your message to many who will be reading this post. I will start by saying that my prayers are with the families of the victims.
Here are some nice points from normative Islamic texts which may answer a good number of your questions and refute a lot of evil that’s being spread:
Al Mughirah ibn Shu’ba used to be mushrik and had friends that were kuffar in the past before he embraced Islam, he killed them and took their money and then went to the Prophet (s) to embrace Islam (also expecting to have his sins forgiven), he said: “I have killed my close friends, and I want to embrace Islam.” The Prophet (s) said: “Islam, we accept from you, as far as the wealth, if it is the wealth of the ghaddar (betrayal) we do not need it from you.”
Imam Sirkhasi said: “It is not allowed for someone, who is under covenant to betray… (if he does betray) he will be on the day of judgement with a banner showing his betrayal, if he betrays and takes money from kuffar and then comes to embrace Islam, his wealth will never be accepted because it was earned in a khabith way.”
Imam Shafi’i said: “If the enemy captures a Muslim and imprisons him, and after that they release him and give him security, and they allow him to live among them, the covenant they give to him is a covenant from him to them (i.e. it is binding on him), it is not allowed for him to assassinate them or betray them, and we do not know any scholar that has mentioned otherwise.” [Kitab ul Umm vol. 4, pg. 292]
On this Imam Al Maqdisi said: “Whenever there is a covenant given to a Muslim in Dar ul-Harb, it is forbidden to harm them or to kill them or take their wealth.” [vol. 10, pg. 555]
Ibn Hamman (Hanbali) said: “If a Muslim enters Dar ul-Harb, as a businessman, or student, it is not allowed for him to touch their life or wealth, because by the covenant he is guarantor that he will never touch them, if he does that, it becomes ghadr, and ghadr is haram by ijma`.” [Al Tahrir, vol. 6, pg. 17]
Furthermore ibn Abideen said, “If a Muslim enters Dar ul-Harb, it becomes forbidden on him to harm their life or wealth or honour, because a Muslim adheres to the covenant… if the money he earns, he earns it in haram, it is not allowed to benefit from it, he should donate it, but if he stole it, he must return it.” [vol. 4, pg. 166]
Imam Sirkhasee said, “If a Muslim enters Dar ul-Harb, and he says to them “I am going to look for a wife” or “to study” or “for trading” or just to pass through the land to go somewhere else, it is agreed that it is a form of customary covenant.” [Al Maqsud]
Note: I don’t consider my home country Dar al-Harb. I left the words there to honor the translation. Thanks to Br. J for hooking me up with this.
