فَإِن رَّجَعَكَ اللّهُ إِلَى طَآئِفَةٍ مِّنْهُمْ فَاسْتَأْذَنُوكَ لِلْخُرُوجِ فَقُل لَّن تَخْرُجُواْ مَعِيَ أَبَدًا وَلَن تُقَاتِلُواْ مَعِيَ عَدُوًّا إِنَّكُمْ رَضِيتُم بِالْقُعُودِ أَوَّلَ مَرَّةٍ فَاقْعُدُواْ مَعَ الْخَالِفِينَ
[9:83]
Therefore if Allah brings you back to a party of them and then they ask your permission to go forth, say: By no means shall you ever go forth with me and by no means shall you fight an enemy with me; surely you chose to sit the first time, therefore sit (now) with those who remain behind.
If, then, Allah bring thee back to any of them, and they ask thy permission to come out (with thee), say: "Never shall ye come out with me, nor fight an enemy with me: for ye preferred to sit inactive on the first occasion: Then sit ye (now) with those who lag behind."
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.
