If only we can conduct a jihadist invasion at least once a year or if possible twice or three times, then many people on earth would become Muslims. And if anyone prevents our dawa or stands in our way, then we must kill them or take as hostage and confiscate their wealth, women and children. Such battles will fill the pockets of the Mujahid who can return home with 3 or 4 slaves, 3 or 4 women and 3 or 4 children. This can be a profitable business if you multiply each head by 300 or 400 dirham. This can be like financial shelter whereby a jihadist, in time of financial need, can always sell one of these heads (meaning slavery).
