﴿ 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.”

And that He might cut off a party of the disbelievers or suppress them so that they fall back frustrated. God does not let enemies gloat over the misfortunes of His friends. Even if the believer is struck by a catastrophic defeat nakba there is no doubt that God will cause His enemy to suffer trial and punishment.
