فَإِن رَّجَعَكَ ٱللَّهُ إِلَىٰ طَآئِفَةٍۢ مِّنْهُمْ فَٱسْتَـْٔذَنُوكَ لِلْخُرُوجِ فَقُل لَّن تَخْرُجُوا۟ مَعِىَ أَبَدًۭا وَلَن تُقَٰتِلُوا۟ مَعِىَ عَدُوًّا ۖ إِنَّكُمْ رَضِيتُم بِٱلْقُعُودِ أَوَّلَ مَرَّةٍۢ فَٱقْعُدُوا۟ مَعَ ٱلْخَٰلِفِينَ
If 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.
Surah At-Tawba(9:83)
