The Prophet ﷺ said, "The one who strives to support the widow and the poor is like the warrior who fights in the cause of Allah." And I believe he also said, "And like the one who stands in prayer without tiring, and like the one who fasts without breaking his fast."
عن النبي ﷺ قال: الساعي على الأرملة والمسكين كالمجاهد في سبيل الله. وأحسبه قال: وكالقائم لا يفتر وكالصائم لا يفطر.
