At-Taubah - 9:46

وَلَوْ أَرَادُواْ الْخُرُوجَ لأَعَدُّواْ لَهُ عُدَّةً وَلَـكِن كَرِهَ اللّهُ انبِعَاثَهُمْ فَثَبَّطَهُمْ وَقِيلَ اقْعُدُواْ مَعَ الْقَاعِدِينَ
[9:46]
And if they had intended to go forth, they would certainly have provided equipment for it, but Allah did not like their going forth, so He withheld them, and it was said (to them): Hold back with those who hold back.
If they had intended to come out, they would certainly have made some preparation therefor; but Allah was averse to their being sent forth; so He made them lag behind, and they were told, "Sit ye among those who sit (inactive)."
And if they had wished to go forth they would assuredly have made ready some equipment, but Allah was averse to their being sent forth and held them back and it was said (unto them): Sit ye with the sedentary!
