وفي سبيل الله: منقطع الغزاة
Translation: For Allah’s cause, the text specifies stranded participants in military expeditions.
“Munqaṭiʿ al-ghuzāt” is a historical legal expression for participants cut off from their resources during the relevant journey. The emphasis in this manual is on their being stranded and in need.
This short medieval rule is not blanket authorisation to fund a present-day armed group or activity.
