﴿ قَٰتِلُوهُمْ يُعَذِّبْهُمُ ٱللَّهُ بِأَيْدِيكُمْ وَيُخْزِهِمْ وَيَنصُرْكُمْ عَلَيْهِمْ وَيَشْفِ صُدُورَ قَوْمٍۢ مُّؤْمِنِينَ ﴾

“Fight against them! God will chastise them by your hands, and will bring disgrace upon them, and will succour you against them; and He will soothe the bosoms of those who believe,”

(Fight them! Allah will chastise them at your hands) He will chastise them by means of your swords, i.e. by killing them, (and He will lay them low) He will abase them by means of defeat (and give you victory over them, and He will heal the breasts of folk who are believers) by the exultation of the Banu Khuza'ah, in that they were allowed to kill their enemies for a while in the Sacred Precinct upon the Conquest of Mecca.
