Kur’an 9:39 — sura At-Tawbah, 39. ajet

إِلَّا تَنفِرُواْ يُعَذِّبۡكُمۡ عَذَابًا أَلِيمٗا وَيَسۡتَبۡدِلۡ قَوۡمًا غَيۡرَكُمۡ وَلَا تَضُرُّوهُ شَيۡـٔٗاۗ وَٱللَّهُ عَلَىٰ كُلِّ شَيۡءٖ قَدِيرٌ

Ako ne budete u boj išli, On će vas na nesnosne muke staviti i drugim će vas narodom zamijeniti, a vi Mu nećete nimalo nauditi. A Allah sve može.

If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent
