Surah At-Tawbah
فَإِن رَّجَعَكَ ٱللَّهُ إِلَىٰ طَآئِفَةٍ مِّنْهُمْ فَٱسْتَـْٔذَنُوكَ لِلْخُرُوجِ فَقُل لَّن تَخْرُجُوا۟ مَعِىَ أَبَدًا وَلَن تُقَـٰتِلُوا۟ مَعِىَ عَدُوًّا ۖ إِنَّكُمْ رَضِيتُم بِٱلْقُعُودِ أَوَّلَ مَرَّةٍ فَٱقْعُدُوا۟ مَعَ ٱلْخَـٰلِفِينَ
Fa ir raja‘akallāhu ilā ṭā'ifatim minhum fasta'żanūka lil-khurūji faqul lan takhrujū ma‘iya abadaw wa lan tuqātilū ma‘iya ‘aduwwā(n), innakum raḍītum bil-qu‘ūdi awwala marrah(tin), faq‘udū ma‘al-khālifīn(a).
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."
