It has been narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) said: One who died but did not fight in the way of Allah nor did he express any desire (or determination) for Jihid died the death of a hypocrite.
'Abdullah b. Mubarak said: We think the hadith pertained to the time of the Messenger of Allah (may peace be upon him).
