Hadrath Abu Hurairah radi Allahu ta’ala anhu reported that The Holy Prophet sallAllahu tala ‘alaihi wa sallam 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 Bukhari Shareef – Volume 7, Book 64, Number 265
