4:84
فَ قَٰتِلْ فِى سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفْسَ كَ وَ حَرِّضِ ٱلْ مُؤْمِنِينَ عَسَى ٱللَّهُ أَن يَكُفَّ بَأْسَ ٱلَّذِينَ كَفَرُ وا۟ وَ ٱللَّهُ أَشَدُّ بَأْسًا وَ أَشَدُّ تَنكِيلًا
So fight, [O Muhammad], in the cause of Allah; you are not held responsible except for yourself. And encourage the believers [to join you] that perhaps Allah will restrain the [military] might of those who disbelieve. And Allah is greater in might and stronger in [exemplary] punishment.
