al-Hasan bin Arfh bin Yazid الحسن بن عرفة بن يزيد · The Chapters on Jihad

“Whoever sends financial support in the cause of Allah and stays at home, for every Dirham he will have (the reward of) seven hundred Dirham. Whoever fights himself in the cause of Allah, and spends on that, for every Dirham he will have (the reward of) seven hundred thousand Dirham.” Then he recited the Verse: “Allah gives manifold increase to whom He wills.”
