The Prophet (ﷺ) said, "The one who looks after a widow or a poor person is like a Mujahid (warrior) who fights for Allah's Cause, or like him who performs prayers all the night and fasts all the day."
Sahih al-Bukhari Book 69, Hadith 3
← Previous Hadith Allah's Messenger (ﷺ) said, "Allah said, 'O son of Adam! Spend, and I shall spend on you."

Sahih al-Bukhari Book 69, Hadith 2 Next Hadith → The Prophet (ﷺ) visited me at Mecca while I was ill. I said (to him), "I have property; May I bequeath all my property in Allah's Cause?" He said, "No." I said, "Half of it?" He said, "No." I said, "One third of it?" He said, "One-third (is alright), yet it is still too much, for you'd better leave your inheritors wealthy than leave them poor, begging of others. Whatever you spend will be considered a Sadaqa for you, even the mouthful of food you put in the mouth of your wife. Anyhow Allah may let you recover, so that some people may benefit by you and others be harmed by you."

Sahih al-Bukhari Book 69, Hadith 4
