“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.”
Sunan Ibn Majah Book 24, Hadith 9
