فَإِن رَّجَعَكَ ٱللَّهُ إِلَىٰ طَآئِفَةٖ مِّنۡهُمۡ فَٱسۡتَـٔۡذَنُوكَ لِلۡخُرُوجِ فَقُل لَّن تَخۡرُجُواْ مَعِيَ أَبَدٗا وَلَن تُقَٰتِلُواْ مَعِيَ عَدُوًّاۖ إِنَّكُمۡ رَضِيتُم بِٱلۡقُعُودِ أَوَّلَ مَرَّةٖ فَٱقۡعُدُواْ مَعَ ٱلۡخَٰلِفِينَ

English Translation
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
