An-Nisa · 4:72

72. There are among you, O Muslims, some people who hesitate to go out to fight your enemies, because of their cowardice, and who also try to keep others behind. They are the hypocrites and who are weak in faith. If you are killed or defeated, then one of them, happy that he is safe, says, ‘Allah has favoured me in that I was not present at the fight with them, otherwise I would have also been harmed like them’.
