Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The one who looks after the needs of a widow and a poor person is like the one who fights in the way of Allah." And I think that he (peace and blessings be upon him) also said: "He is like the one who stands (in prayer at night) without tiring, and like the one who fasts continuously without breaking his fast." Agreed upon.
