Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The example of one who strives in the path of Allah is like that of a person who performs voluntary prayers and fasts continuously, without any break in his prayer and fasting, until the warrior returns, bringing with him spoils and reward, or Allah causes him to die and admits him into Paradise."
