Aal-i-Imraan • EN-TAFSIR-IBN-ABBAS
﴿ لِيَقْطَعَ طَرَفًۭا مِّنَ ٱلَّذِينَ كَفَرُوٓا۟ أَوْ يَكْبِتَهُمْ فَيَنقَلِبُوا۟ خَآئِبِينَ ﴾
“[and] that [through you] He might destroy some of those who were bent on denying the truth, and so abase the others that they would withdraw in utter hopelessness.”
(That He may cut off a part) He says: if He sends His help, it is only in order to kill a group (of those who disbelieve) the unbelievers of Mecca, (or overwhelm them) defeat them (so that they retire, frustrated) not having gained the upper hand or booty.
