If Allah should return you to a faction of them [after the expedition] and then they ask your permission to go out [to battle], say, "You will not go out with me, ever, and you will never fight with me an enemy. Indeed, you were satisfied with sitting [at home] the first time, so sit [now] with those who stay behind."
1 Mufti Taqi Usmani
Then, if Allah brings you back to a group of them and they seek your permission to march, say to them, “You shall never march with me ever after, and shall never fight an enemy in my company. You were happy with sitting back the first time; now, sit with those remaining behind”.
