In a speech by Abdul Malik Mujahid, he puts out a Conference calling for Jihad:

Consider the following statement:

Qital [killing] is an essential element of Islam. And sometimes you don’t like it. Qital is ordained upon you, though it is hateful to you, but it may happen that you hate a thing which is good for you, and it may happen that you love a thing which is bad for you. And one example is, now we have 60 or so Muslim countries, and not a single one of them wants to go for Qital and Jihad for Bosnia. Qital is ordained upon you though it is hateful to you.
