(قَاتِلُوهُمْ يُعَذِّبْهُمُ اللَّهُ بِأَيْدِيكُمْ…)  (Fight them; Allah will punish them by your hands): Allah (swt) is not in need of having the believers to punish them. Allah is capable of sending down punishment upon them from the heavens and relieving the believers of them. However, it is Allah’s wisdom (set ways) in His creation that there are causes in the world. Hence, He (swt) requested the preparation of strength to deter the enemies. Then He says: “And victory is not but from Allah (swt), The Mighty, The Wise.” However, He, Glorified and Exalted, encourages taking the necessary measures.

(…وَيُخْزِهِمْ…) (and will disgrace them): This word means disgrace or humiliation. For some people like Abu Jahl, Al-Walid and others, disgrace is more severe for them than punishment itself.

(…وَيَشْفِ صُدُورَ قَوْمٍ مُّؤْمِنِينَ) (and give you victory over them and satisfy the breasts of a believing people.): Like Abdullah ibn Mas’ud, Bilal, and other early believers who were severely tortured and suffered. In their battle of Badr, Allah (swt) wanted to soothe their hearts after having suffered abuse and oppression.
