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.

O you who believe! be helpers (in the cause) of Allah, as~ Isa son of Marium said to (his) disciples: Who are my helpers in the cause of Allah? The disciples said: We are helpers (in the cause) of Allah. So a party of the children of Israel believed and another party disbelieved; then We aided those who believed against their enemy, and they became uppermost.
