Al-Anfal 8:16

Waman yuwallihim yawma-ithin duburahuilla mutaharrifan liqitalin aw mutahayyizanila fi-atin faqad baa bighadabin mina Allahiwama/wahu jahannamu wabi/sa almaseer

And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allāh, and his refuge is Hell - and wretched is the destination.

Whoever turns his back to them on such a day,- unless it is for a tactic in the battle, or to join a company,-turns with wrath from Allah, and his abode is Jahannam (Hell), and it is an evil place to return.
