(linger behind) means, stays behind and does not join Jihad. It is also possible that this person himself lingers behind, while luring others away from joining Jihad. For instance, Abdullah bin Ubayy bin Salul, may Allah curse him, used to linger behind and lure other people to do the same and refrain from joining Jihad, as Ibn Jurayj and Ibn Jarir stated.

فٳن أصابتكم مصيبة
