Sahih Muslim Book 20, Hadith Number 4696.

Chapter : Denunciation of one who died but never fought in the way of Allah nor did he ever express a desire or determination for jihad.

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).
