Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The likeness of the one who strives in the way of Allah is that of a person who fasts by day and stands in voluntary prayer by night, until he (the mujahid) returns, whenever he returns."
Ahmad, al-Bazzar and al-Tabarani recorded it. The narrators of Ahmad are the narrators of the Sahih.
