The Qur'an tells Muslims to kill non-believers, only in times of war. I saw this post, “We are planning to give Kenyan non-believers a true taste of Jihad." Warriors are taught to kill non-believers any way they can. There is Jihad in the United States, “We are planning to give the United States non-believers a true taste of Jihad." Osama bin Laden declared a war (Jihad) against the United States and I believe that state of war still exists.
What am I to think when a parent says that their son was depressed and that is why he killed.
