{ إن شانئك } أي مُبغضك { هو الأبتر } المنقطع عن كل خير، أو المنقطع العقب، نزلت في العاص بن وائل سمى النبي صلى الله عليه وسلم أبتر عند موت ابنه القاسم.
{Your enemy} meaning the one who hates you {is the one cut off} cut off from all good, or the one whose lineage is cut off. It was revealed about Al-Aas bin Wa’il. The Prophet, may God bless him and grant him peace, called him “cut off” when his son Al-Qasim died.
