فَقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفْسَكَ ۚ وَحَرِّضِ ٱلْمُؤْمِنِينَ ۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأْسَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَٱللَّهُ أَشَدُّ بَأْسًا وَأَشَدُّ تَنكِيلًا 84

So fight, [O Muḥammad], in the cause of Allāh; you are not held responsible except for yourself. And encourage the believers [to join you] that perhaps Allāh will restrain the [military] might of those who disbelieve. And Allāh is greater in might and stronger in [exemplary] punishment.
