فَإِن رَّجَعَكَ ٱللَّهُ إِلَىٰ طَآئِفَةٍۢ مِّنْهُمْ فَٱسْتَـْٔذَنُوكَ لِلْخُرُوجِ فَقُل لَّن تَخْرُجُوا۟ مَعِىَ أَبَدًۭا وَلَن تُقَـٰتِلُوا۟ مَعِىَ عَدُوًّا ۖ إِنَّكُمْ رَضِيتُم بِٱلْقُعُودِ أَوَّلَ مَرَّةٍۢ فَٱقْعُدُوا۟ مَعَ ٱلْخَـٰلِفِينَ

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."

— At-Taubah 9:83
