From Sahih Muslim (Hadith 4931):
It has been narrated on the authority of Abu Huraira that the Messenger of Allah (ﷺ) said:One who died but did not fight in the way of Allah nor did he express any desire (or determination) for Jihad died the death of a hypocrite. 'Abdullah b. Mubarak said: We think the hadith pertained to the time of the Messenger of Allah (ﷺ)
