Hypocrites stay behind
If Allah brings you back to a group of them and they ask to join you, say, “You will never march with me, nor fight an enemy alongside me. You were content to stay behind the first time, so remain with those who lag behind.”
9:83If Allah bring thee back (from the campaign) unto a party of them and they ask of thee leave to go out (to fight), then say unto them: Ye shall never more go out with me nor fight with me against a foe. Ye were content with sitting still the first time. So sit still, with the useless.
