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.

Those who were left behind were glad on account of their sitting behind Allah's Messenger and they were averse from striving m Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it).

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.

And whenever a chapter is revealed, saying: Believe in Allah and strive hard along with His Messenger, those having ampleness of means ask permission of you and say: Leave us (behind), that we may be with those who sit.
