The Holy Quran 9:39 — Surah At-Tawbah

Arabic text

إِلَّا تَنفِرُوا۟ يُعَذِّبْكُمْ عَذَابًا أَلِيمًا وَيَسْتَبْدِلْ قَوْمًا غَيْرَكُمْ وَلَا تَضُرُّوهُ شَيْـًٔا ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

Translation

If you do not go forth, Allaah shall punish you severely and replace you with another nation (who will readily fight in Allaah's path). (By refusing to fight in Allaah's path) You will not be able to harm Allaah in the least (because you will be depriving only yourselves of reward). Allaah has power over all things (and does not need anyone's help).

Tafsir (excerpt) — Tafsir Usmani

that is, the work of Allah does not depend on you. If you are slack, He will by His perfect power raise up some other people to serve the true religion, and you will remain deprived of this good fortune, which will be a loss to none but yourselves.
