وَلَوْ أَرَادُوا الْخُرُوجَ لَأَعَدُّوا لَهُ عُدَّةً وَلَٰكِن كَرِهَ اللَّهُ انبِعَاثَهُمْ فَثَبَّطَهُمْ وَقِيلَ اقْعُدُوا مَعَ الْقَاعِدِينَ
“Had they [really] intended to march forth, they would have made preparations for it. But Allah disliked that they should go, so He let them lag behind, and it was said [to them], "Stay with those [helpless] who remain behind."”
Part of the well-established hypocrites-who-stayed-behind-from-Tabuk passage of Surat al-Tawbah.
