QS. Al-Anfal [8:16]

waman yuwallihim yawma‑idzin duburahu illaa mutaharrifan liqitaalin aw mutahayyizan ilaa fi‑atin faqad baa‑a bighadhabin mina allaahi wama'waahu jahannamu wabi'sa almashiiru

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 Allah, and his refuge is Hell - and wretched is the destination. [16]
