1878. Narrated Aboo Huraira (radhi Allaahu anhu) : The Prophet (Sallallaahu Alaihi Wasallam) said,
The one who looks after a widow or a poor person is like a Mujaahid (Muslim fighter) who fights for Allaah’s cause, or like him who performs Salaat (prayer) all the night and observes Saum (fast) all the day.
