quran:54:45 –

˹Their˺ assembly will be defeated, and they will turn their backs ˹in retreat˺.  

The host will ˹truly˺ be routed and turn its back ˹to flee˺, and so they were defeated at Badr and God’s Messenger (s) was granted victory over them.
القرآن:٥٤:٤٥ –

سَيُهْزَمُ الْجَمْعُ وَيُوَلُّونَ الدُّبُرَ  

{سيهزم الجمع ويولون الدبر} فهزموا ببدر ونصر رسول الله ﷺ عليهم.
