quran:108:3 –

Indeed, your enemy is the one cut off.  

Indeed it is your antagonist, your hater, who is the severed one, refraining from all ˹acts of˺ good, or the one whose line of offspring will be severed ˹by his not having any˺: this was revealed regarding al-‘Āsī b. Wā’il, who called the Prophet (s) al-abtar, ‘the severed one’, when his son al-Qāsim died. Meccan or Medinese, consisting of 6 verses; this was revealed when a band of idolaters said to the Prophet (s), ‘What if you worship our gods for one year, and we worship your God the next?’

إِنَّ شَانِئَكَ هُوَ الْأَبْتَرُ  

{إن شانئك} أي مُبغضك {هو الأبتر} المنقطع عن كل خير، أو المنقطع العقب، نزلت في العاص بن وائل سمى النبي ﷺ أبتر عند موت ابنه القاسم.
