Praise be to Allah.
Jihaad to make the word of Allaah supreme, to protect the religion of Islam, to enable spreading the faith and to protect the things it holds sacred, is an obligation upon everyone who is able to do it. But this necessitates organizing and sending armies, lest it result in chaos leading to bad consequences. So initiating it is one of the tasks of the Muslim ruler, and the ‘ulamaa’ should encourage it. If jihaad begins and the Muslims are mobilized, then everyone who is able should answer the call, sincerely for the sake of Allaah, hoping for truth to prevail and to protect Islam. Whoever holds back from that when the call has been made, with no valid excuse, is a sinner.
And Allaah is the source of strength. May Allaah bless our Prophet Muhammad and his family and companions, and grant them peace.
